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