ALSA: replace CONFIG_PROC_FS with CONFIG_SND_PROC_FS

2015-05-27T19:25:19+00:00

We may disable proc fs only for sound part, to reduce ALSA
memory footprint. So add CONFIG_SND_PROC_FS and replace the
old CONFIG_PROC_FSs in alsa code.

With sound proc fs disabled, we can save about 9KB memory
size on X86_64 platform.

ALSA: core: Clean up OSS proc file management

2015-04-24T15:31:08+00:00

A few minor cleanups:
- Move the call of snd_info_minor_register() into snd_info_init() so
  that we can call all proc-related stuff in a shot
- Add missing __init prefix to snd_info_minor_register()
- Return an error properly from snd_oss_info_register()
- Drop snd_info_minor_unregister() that is superfluous now

ALSA: core: Remove child proc file elements recursively

2015-04-24T15:27:57+00:00

This patch changes the way to manage the resource release of proc
files: namely, let snd_info_free_entry() freeing the whole children.

This makes it us possible to drop the snd_device_*() management.  Then
snd_card_proc_new() becomes merely a wrapper to
snd_info_create_card_entry().

Together with this change, now you need to call snd_info_free_entry()
for a proc entry created via snd_card_proc_new(), while it was freed
via snd_device_free() beforehand.

ALSA: core: Use seq_file for text proc file reads

2015-04-23T15:11:02+00:00

seq_file is _the_ standard interface for simple text proc files.
Though, we still need to support the binary proc files and the text
file write, and also we need to manage the device disconnection
gracefully.  Thus this patch just replaces the text file read code
with seq_file while keeping the rest intact.

snd_iprintf() helper function is now a macro to expand itself to
seq_printf() to be compatible with the existing code.  The seq_file
object is stored to the unused entry->rbuffer->buffer pointer.

When the output size is expected to be large (greater than PAGE_SIZE),
the driver should set entry->size field beforehand.  Then the given
size will be preallocated and the multiple show calls can be avoided.

treewide: use printf not attribute__((format(printf,...)))

2011-11-01T00:30:54+00:00

Standardize the style for compiler based printf format verification.
Standardized the location of __printf too.

Done via script and a little typing.

$ grep -rPl --include=*.[ch] -w "__attribute__" * | \
  grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \
  xargs perl -n -i -e 'local $/; while (<>) { s/\b__attribute__\s*\(\s*\(\s*format\s*\(\s*printf\s*,\s*(.+)\s*,\s*(.+)\s*\)\s*\)\s*\)/__printf($1, $2)/g ; print; }'
