sound: oss: dmasound: remove software_input_volume declaration

2022-09-09T07:11:06Z

expand_read_bal has been removed since commit fc37449f7959 ("The next round of scheduled OSS code removal"). software_input_volume has been removed since commit 0a1b42db4bf9 ("sound: sound/oss/dmasound/: cleanups"). so remove the declare for them from header file.

sound/oss/dmasound: fix 'dmasound_setup' defined but not used

2022-04-15T07:17:37Z

We observed: 'dmasound_setup' defined but not used error with COMPILER=gcc ARCH=m68k DEFCONFIG=allmodconfig build. Fix it by adding __maybe_unused to dmasound_setup.

sound/oss/dmasound: fix build when drivers are mixed =y/=m

2022-04-07T08:28:48Z

When CONFIG_DMASOUND_ATARI=m and CONFIG_DMASOUND_Q40=y (or vice versa), dmasound_core.o can be built without dmasound_deinit() being defined, causing a build error: ERROR: modpost: "dmasound_deinit" [sound/oss/dmasound/dmasound_atari.ko] undefined! Modify dmasound_core.c and dmasound.h so that dmasound_deinit() is always available. The mixed modes (=y/=m) also mean that several variables and structs have to be declared in all cases.

ALSA: Convert strlcpy to strscpy when return value is unused

2021-01-08T08:30:05Z

strlcpy is deprecated. see: Documentation/process/deprecated.rst Change the calls that do not use the strlcpy return value to the preferred strscpy. Done with cocci script: @@ expression e1, e2, e3; @@ - strlcpy( + strscpy( e1, e2, e3); This cocci script leaves the instances where the return value is used unchanged. After this patch, sound/ has 3 uses of strlcpy() that need to be manually inspected for conversion and changed one day. $ git grep -w strlcpy sound/ sound/usb/card.c: len = strlcpy(card->longname, s, sizeof(card->longname)); sound/usb/mixer.c: return strlcpy(buf, p->name, buflen); sound/usb/mixer.c: return strlcpy(buf, p->names[index], buflen); Miscellenea: o Remove trailing whitespace in conversion of sound/core/hwdep.c Link: https://lore.kernel.org/lkml/CAHk-=wgfRnXz0W3D37d01q3JFkr_i_uTL=V6A6G1oUZcprmknw@mail.gmail.com/ Signed-off-by: Joe Perches Acked-by: Mark Brown Link: https://lore.kernel.org/r/22b393d1790bb268769d0bab7bacf0866dcb0c14.camel@perches.com Signed-off-by: Takashi Iwai

ALSA: Use fallthrough pseudo-keyword

2020-07-09T11:01:29Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

compat_ioctl: remove translation for sound ioctls

2019-10-23T15:23:45Z

The SNDCTL_* and SOUND_* commands are the old OSS user interface. I checked all the sound ioctl commands listed in fs/compat_ioctl.c to see if we still need the translation handlers. Here is what I found: - sound/oss/ is (almost) gone from the kernel, this is what actually needed all the translations - The ALSA emulation for OSS correctly handles all compat_ioctl commands already. - sound/oss/dmasound/ is the last holdout of the original OSS code, this is only used on arch/m68k, which has no 64-bit mode and hence needs no compat handlers - arch/um/drivers/hostaudio_kern.c may run in 64-bit mode with 32-bit x86 user space underneath it. This rare corner case is the only one that still needs the compat handlers. By adding a simple redirect of .compat_ioctl to .unlocked_ioctl in the UML driver, we can remove all the COMPATIBLE_IOCTL() annotations without a change in functionality. For completeness, I'm adding the same thing to the dmasound file, knowing that it makes no difference. The compat_ioctl list contains one comment about SNDCTL_DSP_MAPINBUF and SNDCTL_DSP_MAPOUTBUF, which actually would need a translation handler if implemented. However, the native implementation just returns -EINVAL, so we don't care. Reviewed-by: Takashi Iwai Signed-off-by: Arnd Bergmann

sound: dmasound_atari: Mark expected switch fall-through

2019-07-30T07:36:13Z

Mark switch cases where we are expecting to fall through. This patch fixes the following warning (Building: m68k): sound/oss/dmasound/dmasound_atari.c: warning: this statement may fall through [-Wimplicit-fallthrough=]: => 1449:24 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find.

docs: kbuild: convert docs to ReST and rename to *.rst

2019-06-14T20:21:21Z

The kbuild documentation clearly shows that the documents there are written at different times: some use markdown, some use their own peculiar logic to split sections. Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Jonathan Corbet
