Subject: [patch] nfc: signedness bug in __nci_request()
Date: Fri, 09 Dec 2011 06:35:39 +0000 [thread overview]
Message-ID: <20111209063539.GA20287@elgon.mountain> (raw)
wait_for_completion_interruptible_timeout() returns -ERESTARTSYS if
interrupted so completion_rc needs to be signed. The current code
probably returns -ETIMEDOUT if we hit this situation, but after this
patch is applied it will return -ERESTARTSYS.
