Build error after 6d06fcc2 (a typo?)

[asavah]

After 6d06fcc the build fails.

Some insightful warnings:

pcm_dmix.c: In function ‘snd_pcm_dmix_rewind’:

Note the difference between pcm_frames_diff (typo?) and pcm_frame_diff (as defined in the header)

Yep, typo. Fixed in 0128af6 . Thanks for the report.
