Subject: motech-lps-30x: Mark serial read call as nonblocking.
X-Git-Tag: libsigrok-0.4.0~951
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=e050124095c3e0109ead1fc162504cc513a4e08c;p=libsigrok.git

motech-lps-30x: 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.
