build sound/sound_firmware.c only for OSS
RFC PATCH 1/1 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.
