Subject: [PATCH net RFT] ch9200: do return USB errors from control_write()
Date: Fri, 4 Sep 2026 23:01:07 +0300 [thread overview]
Message-ID: <20260904200108.85165-1-s.shtylyov@auroraos.dev> (raw)
Compared with control_read(), control_write() looks really strange:
it ignores any errors returned by usb_control_msg(), always returning
0 instead, despite overriding a positive result of usb_control_msg()
(indicating short transfer) to -EINVAL before doing that. Drop that
dubious *return* and propagate USB errors to the callers...
Fixes: 4a476bd6d1d9 ("usbnet: New driver for QinHeng CH9200 devices")
