| * Rationalize fasync return valuesJonathan Corbet2009-03-161-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

* | sony-laptop: fix event reporting for new style eventsMatthias Welwarsky2009-04-031-18/+23
| | | | | | | | | | | | | | | | | | | | | | | | In short Fn key events are always reported through acpi. The input layer gets all the old style events and only those new style events that, after being decoded, are mapped to an locally represented events. rfkill only update the rfkill device status.

* | sony-laptop: merge Type4 into Type3Mattia Dongili2009-03-271-22/+6
| | | | | | | | | | | | | | | | | | | | Creating Type4 was a mistake in the first place. Some users report that also Type3 vaios require the same extra hotkey handling which the Type4 for was menat to guard from. Merging down Type4 into Type3 will just remove a useless distinction.

| | | | | | | | | | | | | | | | | | | | | | The latest Vaios can execute certain codepaths in two ways - either using system management mode or using pure ACPI methods.

* | sony-laptop: Add support for new Sony platform APIMatthew Garrett2009-03-271-81/+65
|/ | | | | | | | | | | | Newer Sony Vaios provide a new API for accessing platform functionality. It consists of a set of standardised methods for enabling events and performing queries. These are each identified by a unique handle. This patch adds support for calling functions based on their handle and ports the existing code for these machines over to it.

* create drivers/platform/x86/ from drivers/misc/Len Brown2008-12-191-0/+2781
Move x86 platform specific drivers from drivers/misc/ to a new home under drivers/platform/x86/. The community has been maintaining x86 vendor-specific platform specific drivers under /drivers/misc/ for a few years. The oldest ones started life under drivers/acpi. They moved out of drivers/acpi/ because they don't actually implement the ACPI specification, but either simply use ACPI, or implement vendor-specific ACPI extensions. In the future we anticipate... drivers/misc/ will go away. other architectures will create drivers/platform/<arch> Signed-off-by: Len Brown <len.brown@intel.com>
