2015-03-06ALSA: opl3: small array underflowDan Carpenter1-0/+2
There is a missing lower bound check on "pitchbend" so it means we can read up to 6 elements before the start of the opl3_note_table[] array. Thanks to Clemens Ladisch for his help with this patch. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-01-04ALSA: Deletion of checks before the function call "iounmap"Markus Elfring1-2/+1
The iounmap() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-02ALSA: ml403-ac97cr: Remove always NULL parameterLars-Peter Clausen1-7/+2
snd_ml403_ac97cr_pcm() takes a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM is stored. All callers pass NULL though, so remove the parameter.

Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers.

2014-02-10ALSA: Replace with IS_ENABLED()Takashi Iwai1-1/+1
Replace the lengthy #if defined(XXX) || defined(XXX_MODULE) with the new IS_ENABLED() macro. The patch still doesn't cover all ifdefs. For example, the dependency on CONFIG_GAMEPORT is still open-coded because this also has an extra dependency on MODULE. Similarly, an open-coded ifdef in pcm_oss.c and some sequencer-related stuff are left untouched. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2013-01-25ALSA: Make snd_printd() and snd_printdd() inlineTakashi Iwai1-2/+1
Because currently snd_printd() and snd_printdd() macros are expanded to empty when CONFIG_SND_DEBUG=n, a compile warning like below appears sometimes, and we had to covert it by ugly ifdefs: sound/pci/hda/patch_sigmatel.c: In function ‘stac92hd71bxx_fixup_hp’: sound/pci/hda/patch_sigmatel.c:2434:24: warning: unused variable ‘spec’ [-Wunused-variable] For "fixing" these issues better, this patch replaces snd_printd() and snd_printdd() definitions with empty inline functions instead of macros. This should have the same effect but shut up warnings like above. But since we had already put ifdefs, changing to inline functions would trigger compile errors. So, such ifdefs is removed in this patch. In addition, snd_pci_quirk name field is defined only when CONFIG_SND_DEBUG_VERBOSE is set, and the reference to it in snd_printdd() argument triggers the build errors, too. For avoiding these errors, introduce a new macro snd_pci_quirk_name() that is defined no matter how the debug option is set.
