From b3404a8ef567de43b74018bbdbd989b53426d422 Mon Sep 17 00:00:00 2001 From: Frank Schaefer Date: Mon, 8 Apr 2013 13:06:59 -0300 Subject: [PATCH] [media] em28xx: save isoc endpoint number for DVB only if endpoint has alt settings with xMaxPacketSize != 0 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit X-Patchwork-Delegate: mchehab@redhat.com In addition to commit 72cc9ba3 "em28xx: ignore isoc DVB USB endpoints with wMaxPacketSize = 0 bytes for all alt settings" we should not save the endpoint number of the isoc DVB endpoint before it has been validated. While the current code works fine, dev->dvb_ep_isoc != 0 could be interpreted as indicator that the device provides DVB support.
