Subject: [PATCH v3 0/2] reducing memory footprint of ALSA

We are planning to work on reducing memory footprint of ALSA,
targeting on small memory embedded devices(e.g. IoT), this
series focuses on disabling procfs, hw/sw params refinement,
mmap, dpcm, dapm, compressed API, compat code APIs...

We plan to enable those reducing items only for EXPERT, and
add knobs in sound/core/Kconfig.

These first two patches is a start, adding SND_PROC_FS to config
disable/enable ALSA proc FS, this disabling can save about 9KB
code size on x86_64 platform.

Changes in v3:
1. drop SND_REDUCED_MEMORY_FOOTPRINT and make configuration
available only for EXPERT;
2. move the configure into sound/core/Kconfig;
3. Add missing Signed-off-by for PATCH 2/2.

Changes in v2:
1. Prompt "Sound Proc FS Support" appears only when
SND_REDUCED_MEMORY_FOOTPRINT is true.

Jie Yang (2):
  ALSA: Kconfig: add config item SND_PROC_FS for expert
  ALSA: replace CONFIG_PROC_FS with CONFIG_SND_PROC_FS
