Subject: gmc-mh-1x-2x: Mark serial read call as nonblocking.
X-Git-Tag: libsigrok-0.4.0~959
X-Git-Url: https://sigrok.org/gitweb/?a=commitdiff_plain;h=0714a010ccd12514861eb24411fdb156299658a9;hp=bb27c76513c887ad28bbafafb34858ee2e548c6d;p=libsigrok.git

gmc-mh-1x-2x: Mark serial read call as nonblocking.

This call was already nonblocking since the driver opens the port with the
SERIAL_NONBLOCK flag. It only reads one byte, and a zero result is handled
appropriately.
