+Subject: [PATCH] Update iatomic.h functions definitions for mips
+
+Functions atomic_add(s) and atomic_sub(s) are defined with 'extern
+__inline__' that may cause compile fails when cross compile for mips.
+The error message looks like:
+
+| pcm/.libs/libpcm.a(pcm_meter.o): In function `snd_pcm_meter_update_scope':
+| .../alsa-lib-1.0.27.2/src/pcm/pcm_meter.c:139: undefined reference to `atomic_sub'
+
+Replace the 'extern __inline__' with 'static __inline__' to fix this
+issue.
