Subject: V4L/DVB (6624): CXUSB: return control message transfer result to caller
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b17f109df1cd9fe1009501d59e466701106590d7;p=deliverable%2Flinux.git

V4L/DVB (6624): CXUSB: return control message transfer result to caller

Callers to cxusb_ctrl_msg currently do not receive any indication that their
transfer failed.  Return the true return code from dvb_usb_generic_{rw,write}.
