Subject: [PATCH] build sound/sound_firmware.c only for OSS
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b9dd6ffc3d6b56417a2c4c917f51dab6470166e6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] build sound/sound_firmware.c only for OSS

All sound/sound_firmware.c contains is mod_firmware_load() that is a legacy
API only used by some OSS drivers.

This patch builds it into an own sound_firmware module that is only built
depending on CONFIG_SOUND_PRIME making the kernel slightly smaller for ALSA
users.
