Make this const as it only passed as the 1st argument to the function
snd_ctl_new1, which is of type const.
Done using Coccinelle.

Usually, I don't like fixing coding style issues on non-staging
drivers, as it could be a mess pretty easy, and could become like
a snow ball. That's the case of recent changes on two changesets:
they disalign some statements. Yet, a care a lot with cx88 driver,
as it was the first driver I touched at the Kernel, and I've been
maintaining it since 2005. So, several of the coding style issues
were due to my code.
Per Andrey's suggestion, I ran checkpatch.pl in strict mode, with
fixed several other issues, did some function alinments, but broke
other alinments.
So, I had to manually apply another round of manual fixes to make
sure that everything is ok, and to make checkpatch happy with
this patch.
With this patch, checkpatch.pl is now happy when called with:
./scripts/checkpatch.pl -f --max-line-length=998 --ignore PREFER_PR_LEVEL
Also, the 80-cols violations that made sense were fixed.
Checkpatch would be happier if we convert it to use dev_foo(),
but this is a more complex change.
NOTE: there are some places with msleep(1). As this driver was
written at the time that the default was to sleep at least 10ms
on such calls (e. g. CONFIG_HZ=100), I replaced those calls by
usleep_range(10000, 20000), with should be safe to avoid breakages.
Fixes: 65bc2fe86e66 ("[media] cx88: convert it to use pr_foo() macros")
Fixes: 7b61ba8ff838 ("[media] cx88: make checkpatch happier")

This driver is old, and have lots of checkpatch violations.
As we're touching a lot on this driver due to the printk
conversions, let's run checkpatch --fix on it, in order to
solve some of those issues.
Also, do a few manual adjustments:
- remove the FSF address and use the usual coding style
for the initial comments;
- use WARN_ON() instead of BUG_ON();
- remove an unused typedef;
- break a few long lines.

Instead of calling printk() directly, use pr_foo()
macros, as suggested at the Kernel's coding style.
Please notice that a conversion to dev_foo() is not trivial,
as several parts on this driver uses pr_cont().

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. 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>

while (<>) {
if ($next ne "") {
$c=$_;
if ($c =~ /^\s+\"(.*)/) {

Check for snd_pcm_ops structures that are only stored in the ops field of a
snd_soc_platform_driver structure or passed as the third argument to
snd_pcm_set_ops. The corresponding field or parameter is declared const,
so snd_pcm_ops structures that have this property can be declared as const
also.
The semantic patch that makes this change is as follows:

pci_set_dma_mask returns a negative errno value, not a bool like

Currently, include/media is messy, as it contains both the V4L2 core
headers and some driver-specific headers on the same place. That makes
harder to identify what core headers should be documented and what
headers belong to I2C drivers that are included only by bridge/main
drivers that would require the functions provided by them.
Let's move those i2c specific files to its own subdirectory.
The files to move were produced via the following script:
mkdir include/media/i2c
(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done
And the references corrected via this script:
MAIN_DIR="media/"
PREV_DIR="media/"
DIRS="i2c/"
echo "Checking affected files" >&2
for i in $DIRS; do
for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
n=`basename $j`
git grep -l $n
done
done|sort|uniq >files && (
echo "Handling files..." >&2;
echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
(
cd include/$MAIN_DIR;
for j in $DIRS; do
for i in $(ls $j); do
echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
done;
done;
echo "cat > a && mv a \$i; done";
);
echo "Handling documentation..." >&2;
echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
(
cd include/$MAIN_DIR;
for j in $DIRS; do
for i in $(ls $j); do
echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
done;

echo "cat > a && mv a \$i; done"

This fixes a NULL pointer deference when loading the cx88_dvb module for a
Hauppauge HVR4000.
The bugzilla bug report is here:
https://bugzilla.kernel.org/show_bug.cgi?id=56271
The cause is that the wm8775 is optional, so even though the board info says
there is one, it doesn't have to be there. Checking whether the module was
actually loaded is much safer.
Note that this driver is quite buggy when it comes to unloading and reloading
modules. Unloading cx8800 and reloading it again will still cause a crash,
most likely because either the i2c bus isn't unloaded at the right time and/or
the v4l2_device_unregister isn't called at the right time.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
