2009-03-18ALSA: Fix vunmap and free order in snd_free_sgbuf_pages()Takashi Iwai
In snd_free_sgbuf_pags(), vunmap() is called after releasing the SG pages, and it causes errors on Xen as Xen manages the pages differently. Although no significant errors have been reported on the actual hardware, this order should be fixed other way round, first vunmap() then free pages.

2009-03-18ALSA: oss-mixer - Fixes recording gain controlViral Mehta
At the time of initialization, SNDRV_MIXER_OSS_PRESENT_PVOLUME bit is not set for MIC (slot 7). So, the same should not be checked when an application tries to do gain control for audio recording devices. Just check slot->present for SNDRV_MIXER_OSS_PRESENT_CVOLUME independently. Verified with a simple application which opens /dev/dsp for recording and /dev/mixer for volume control. Have tested two usb audio mic devices.

2009-02-18ALSA: jack - Use card->shortname for input nameTakashi Iwai
Currently the jack layer refers to card->longname as a part of its input device name string. However, longname is often really long and way too ugly as an identifier, such as, "HDA Intel at 0xf8400000 irq 21". This patch changes the code to use card->shortname instead. The shortname string contains usually the h/w vendor and product names but without messy I/O port or IRQ numbers. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-01-06Check fops_get() return valueLaurent Pinchart
Several subsystem open handlers dereference the fops_get() return value without checking it for nullness. This opens a race condition between the open handler and module unloading. A module can be marked as being unloaded (MODULE_STATE_GOING) before its exit function is called and gets the chance to unregister the driver. During that window open handlers can still be called, and fops_get() will fail in try_module_get() and return a NULL pointer. This change checks the fops_get() return value and returns -ENODEV if NULL.

2008-11-01saner FASYNC handling on file closeAl Viro
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.
