a4f508b27c [ALSA] rtctimer: add option to make RTC timer the default sequencer timer
ALSA Core,ALSA sequencer
Add an option to make the RTC timer the default sequencer timer.  This

ecbcfe36fa [ALSA] Introduce snd_card_set_generic_dev()
ALSA Core
A new function snd_card_set_generic_dev() is introduced to add the
'generic device' support for devices without proper bus on sysfs.
It's a last resort, and should be removed in future when they have
a proper bus, instead.

77933d7276 [PATCH] clean up inline static vs static inline
`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration.  This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).

While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

543537bd92 [PATCH] create a kstrdup library function
This patch creates a new kstrdup library function and changes the "local"
implementations in several places to use this function.

Most of the changes come from the sound and net subsystems.  The sound part
had already been acknowledged by Takashi Iwai and the net part by David S.
Miller.

I left UML alone for now because I would need more time to read the code
carefully before making changes there.
