Subject: [PATCH 1/1] bluetooth: propagate the error code
Date: Thu, 1 Dec 2016 14:23:29 +0800 [thread overview]
Message-ID: <1480573409-18520-1-git-send-email-bianpan2016@163.com> (raw)
Fix bug https://bugzilla.kernel.org/show_bug.cgi?id=188551. A negative
return value means there are errors, while 0 indicates success. However,
in function bpa10x_send_frame(), it returns 0 no matter whether
usb_submit_urb() returns a negative value. As a result, the caller of
bpa10x_send_frame() may not detect the submission error. In this patch,
use "return err;" at the end to propagate the error.
