Subject: axfer: fix to return error code when a call of select(2) fails
X-Git-Tag: v1.2.1~10
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=1c17128410c09f74ef41b71abe77215193c5cdaf;p=alsa-utils.git

axfer: fix to return error code when a call of select(2) fails

A call of select(2) returns negative code and report errors via errno
local variable, howver current waiter implementation for select(2)
returns the negative code instead of errno.

This commit fixes it.
