Subject: [PATCH v2 2/3] media: dvbsky: Remove duplicate error reporting for dvbsky_usb_generic_rw
Date:   Sun, 19 May 2019 13:18:30 +0200

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Errors are already reported by the common code in dvb_usb_v2_generic_io
(which dvbsky_usb_generic_rw is a wrapper of), so there is no reason
report the error again.
