Before this commit, compilation of `pcm_share` causes warnings "ignoring return value" for several `read` and `write` operations:

pcm_share.c: In function '_snd_pcm_share_missing':
pcm_share.c:293:5: warning: ignoring return value of 'read', declared with
attribute warn_unused_result [-Wunused-result]
     read(share->slave_socket, buf, 1);
     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Which compiler version? I'm using gcc 8.2.1, and couldn't get any warnings like the above.

thanks,

Takashi

My gcc version is 6.4.0

Best Regards, Kirill
