Subject: center-3xx: Mark serial read call as nonblocking.
X-Git-Tag: libsigrok-0.4.0~968
X-Git-Url: http://sigrok.org/gitweb/?a=commitdiff_plain;h=3582ce8a01ef4f4befd3fccc28c5788196d48499;p=libsigrok.git

center-3xx: Mark serial read call as nonblocking.

This call was already nonblocking because the driver opens the port with the
SERIAL_NONBLOCK flag. Partial reads are handled.
