Subject: brymen-dmm: Make serial write call block.
X-Git-Tag: libsigrok-0.4.0~971
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=776313d997f1748ff89cb073f45e3560ad661136

brymen-dmm: Make serial write call block.

This call is executed from an event handler and was previously nonblocking,
but has no partial write handling. It sends a short packet so should be OK
to block, most likely the output buffer will be empty anyway.
