2020-12-25	ALSA: oss: Use DIV_ROUND_CLOSEST() instead of open-coding it	Lars-Peter Clausen	1	-2/+2
	Use DIV_ROUND_CLOSEST() instead of open-coding it. This documents intent and makes it more clear what is going on for the casual reviewer. Generated using the following the Coccinelle semantic patch. // <smpl> @@ expression x, y; @@ -((x) + ((y) / 2)) / (y) +DIV_ROUND_CLOSEST(x, y) // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Link: https://lore.kernel.org/r/20201223172229.781-13-lars@metafoo.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2020-02-12	ALSA: core: Replace zero-length array with flexible-array member	Gustavo A. R. Silva	1	-1/+1
	The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertenly introduced[3] to the codebase from now on. This issue was found with the help of Coccinelle.

2019-05-24	ALSA: pcm: oss: Use struct_size() helper	Gustavo A. R. Silva	1	-2/+2
	Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace the following form: sizeof(struct rate_priv) + src_format->channels * sizeof(struct rate_channel) with: struct_size(data, channels, src_format->channels) This code was detected with the help of Coccinelle.

2009-02-23	ALSA: fix excessive background noise introduced by OSS emulation rate shrink	Steve Chen	1	-1/+1
	Incorrect variable was used to get the next sample which caused S2 to be stuck with the same value resulting in loud background noise. Signed-off-by: Steve Chen <schen at mvista.com> Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-08-13	ALSA: Kill snd_assert() in sound/core/*	Takashi Iwai	1	-16/+26
	Kill snd_assert() in sound/core/*, either removed or replaced with if () with snd_BUG_ON(). Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-01-31	[ALSA] Remove sound/driver.h	Takashi Iwai	1	-1/+0
	This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

2007-10-16	[ALSA] Remove ifdefs from OSS PCM emulation codes	Takashi Iwai	1	-5/+0
	Fix Makefile to compile files conditionally to CONFIG_SND_PCM_OSS_PLUGINS, and remove unneeded ifdefs in these files. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-03-22	[ALSA] Clean up pcm-oss plugins	Takashi Iwai	1	-60/+20

	Modules: ALSA Core,PCM Midlevel,ALSA<-OSS emulation,USB generic driver 1) The verbose procfs code for the PCM midlevel and usb audio can be removed now (more patches will follow). CONFIG_SND_VERBOSE_PROCFS 2) The PCM OSS plugin system can be also compiled optionaly. CONFIG_SND_PCM_OSS_PLUGINS Signed-off-by: Jaroslav Kysela <perex@suse.cz>

2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-0/+378
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
