2015-01-02ALSA: gus: Remove always NULL parametersLars-Peter Clausen
snd_gf1_pcm_new() and snd_gf1_rawmidi_new() take a pointer to a pointer of a PCM/MIDI where if this parameter is provided the newly allocated object is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit cleaner and shorter. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-01-02ALSA: es1688: Remove almost always NULL parameterLars-Peter Clausen
snd_es1688_pcm() takes a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM is stored. This PCM is also available from the pcm field of the snd_es1688 struct that got passed to the same function. This patch updates all callers which passed a pointer to use that field instead and then removes the parameter from the function. This makes the code a bit shorter and cleaner.

git://git.kernel.org/pub/scm/linux/kernel/git/luto/linux into x86/urgent Pull VDSO fix from Andy Lutomirski: "This is hopefully the last vdso fix for 3.19. It should be very safe (it just adds a volatile). I don't think it fixes an actual bug (the __getcpu calls in the pvclock code may not have been needed in the first place), but discussion on that point is ongoing. It also fixes a big performance issue in 3.18 and earlier in which the lsl instructions in vclock_gettime got hoisted so far up the function that they happened even when the function they were in was never called. n 3.19, the performance issue seems to be gone due to the whims of my compiler and some interaction with a branch that's now gone. I'll hopefully have a much bigger overhaul of the pvclock code for 3.20, but it needs careful review." Signed-off-by: Ingo Molnar <mingo@kernel.org>

2014-12-30Revert "cfg80211: make WEXT compatibility unselectable"Jiri Kosina
This reverts commit 24a0aa212ee2dbe44360288684478d76a8e20a0a. It's causing severe userspace breakage. Namely, all the utilities from wireless-utils which are relying on CONFIG_WEXT (which means tools like 'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw' utility in newer wireless-tools, which is supposed to be a replacement for all the "deprecated" binaries, but it's far away from being massively adopted. Please see [1] for example of the userspace breakage this is causing. In addition to that, Larry Finger reports [2] that this patch is also causing ipw2200 driver being impossible to build. To me this clearly shows that CONFIG_WEXT is far, far away from being "deprecated enough" to be removed.

2014-12-30SCSI: fix regression in scsi_send_eh_cmnd()Alan Stern
Commit ac61d1955934 (scsi: set correct completion code in scsi_send_eh_cmnd()) introduced a bug. It changed the stored return value from a queuecommand call, but it didn't take into account that the return value was used again later on. This patch fixes the bug by changing the later usage. There is a big comment in the middle of scsi_send_eh_cmnd() which does a good job of explaining how the routine works. But it mentions a "rtn = FAILURE" value that doesn't exist in the code. This patch adjusts the code to match the comment (I assume the comment is right and the code is wrong). This fixes Bugzilla #88341.

This gets rids one of the few users of the custom ld2() function and also makes it a bit more obvious what the code does.
