Subject: [PATCH 11/13] brcmfmac: assure brcmf_txcomplete() is called in failure paths
Date: Sun, 3 Mar 2013 12:45:30 +0100 [thread overview]
Message-ID: <1362311132-29561-12-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1362311132-29561-1-git-send-email-arend@broadcom.com>
For transmit packets the function brcmf_txcomplete() must be
called. This should be done as well when for some reason the
transmit fails to assure proper tx post processing. This patch
fixes the code paths in brcmf_usb_tx() that forgot to do so.
