This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

* [media] af9035: fix dual tuner detection with PCTV 79eStefan Pöschel2016-07-152-18/+34
| | | | | | | | | | | | | | | The value 5 of the EEPROM_TS_MODE register (meaning dual tuner presence) is only valid for AF9035 devices. For IT9135 devices it is invalid and led to a false positive dual tuner mode detection with PCTV 79e. Therefore on non-AF9035 devices and with value 5 the driver now defaults to single tuner mode and outputs a regarding info message to log. This fixes Bugzilla bug #118561.

(Thanks to Bruce for noticing the zero-length corner case) - Converts the string hashes in <linux/sunrpc/svcauth.h> to use the above. - Avoids 64-bit multiplies in hash_64() on 32-bit platforms. Two 32-bit multiplies will do well enough. - Rids the world of the bad hash multipliers in hash_32. This finishes the job started in commit 689de1d6ca95 ("Minimal fix-up of bad hashing behavior of hash_64()") The vast majority of Linux architectures have hardware support for 32x32-bit multiply and so derive no benefit from "simplified" multipliers. The few processors that do not (68000, h8/300 and some models of Microblaze) have arch-specific implementations added. Those patches are last in the series. - Overhauls the dcache hash mixing. The patch in commit 0fed3ac866ea ("namei: Improve hash mixing if CONFIG_DCACHE_WORD_ACCESS") was an off-the-cuff suggestion. Replaced with a much more careful design that's simultaneously faster and better. (My own invention, as there was noting suitable in the literature I could find. Comments welcome!) - Modify the hash_name() loop to skip the initial HASH_MIX(). This would let us salt the hash if we ever wanted to. - Sort out partial_name_hash(). The hash function is declared as using a long state, even though it's truncated to 32 bits at the end and the extra internal state contributes nothing to the result. And some callers do odd things: - fs/hfs/string.c only allocates 32 bits of state - fs/hfsplus/unicode.c uses it to hash 16-bit unicode symbols not bytes - Modify bytemask_from_count to handle inputs of 1..sizeof(long) rather than 0..sizeof(long)-1. This would simplify users other than full_name_hash" Special thanks to Bruce Fields for testing and finding bugs in v1. (I learned some humbling lessons about "obviously correct" code.) On the arch-specific front, the m68k assembly has been tested in a standalone test harness, I've been in contact with the Microblaze maintainers who mostly don't care, as the hardware multiplier is never omitted in real-world applications, and I haven't heard anything from the H8/300 world" * 'hash' of git://ftp.sciencehorizons.net/linux: h8300: Add <asm/hash.h> microblaze: Add <asm/hash.h> m68k: Add <asm/hash.h> <linux/hash.h>: Add support for architecture-specific functions fs/namei.c: Improve dcache hash function Eliminate bad hash multipliers from hash_32() and hash_64() Change hash_64() return value to 32 bits <linux/sunrpc/svcauth.h>: Define hash_str() in terms of hashlen_string() fs/namei.c: Add hashlen_string() function Pull out string hash to <linux/stringhash.h>
| * Eliminate bad hash multipliers from hash_32() and hash_64()George Spelvin2016-05-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "simplified" prime multipliers made very bad hash functions, so get rid of them. This completes the work of 689de1d6ca. To avoid the inefficiency which was the motivation for the "simplified" multipliers, hash_64() on 32-bit systems is changed to use a different algorithm. It makes two calls to hash_32() instead. drivers/media/usb/dvb-usb-v2/af9015.c uses the old GOLDEN_RATIO_PRIME_32 for some horrible reason, so it inherits a copy of the old definition.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The root i2c adapter lock is then no longer held by the i2c mux during accesses behind the i2c gate, and such accesses need to take that lock just like any other ordinary i2c accesses do. So, declare the i2c gate mux-locked, and zap the regmap overrides that makes the i2c accesses unlocked and use plain old regmap accesses. This also removes the need for the regmap wrappers used by rtl2832_sdr, so deconvolute the code further and provide the regmap handle directly instead of the wrapper functions.

| | | | | | | | | | | | | | | | | Instead of using the DTV properties cache directly, pass the get frontend data as an argument. For now, everything should remain the same, but the next patch will prevent get_frontend to affect the global cache. This is needed because several drivers don't care enough to only change the properties if locked. Due to that, calling G_PROPERTY before locking on those drivers will make them to never lock. Ok, those drivers are crap and should never be merged like that, but the core should not rely that the drivers would be doing the right thing.

* [media] rtl28xxu: retry failed i2c messagesAntti Palosaari2016-02-011-0/+8
| | | | | | | | | | | | | | Sometimes i2c transfer fails. That happens especially when large amount of data is written sequentially eg. firmware download. Problem arises with both integrated rtl2832 demod and external mn88472 demod, which is clear indicator it is busy i2c bus issue. Use i2c core retry logic in order fix the issue by repeating failed message. Another solution which also works is to add ~100us delay between i2c messages - but repeating sounds more elegant and does not cause any extra delay for success cases.

* [media] media-device: split media initialization and registrationJavier Martinez Canillas2016-01-111-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | The media device node is registered and so made visible to user-space before entities are registered and links created which means that the media graph obtained by user-space could be only partially enumerated if that happens too early before all the graph has been created. To avoid this race condition, split the media init and registration in separate functions and only register the media device node when all the pending subdevices have been registered, either explicitly by the driver or asynchronously using v4l2_async_register_subdev(). The media_device_register() had a check for drivers not filling dev and model fields but all drivers in mainline set them and not doing it will be a driver bug so change the function return to void and add a BUG_ON() for dev being NULL instead. Also, add a media_device_cleanup() function that will destroy the graph_mutex that is initialized in media_device_init().
