From 37571b163c15831cd0a213151c21387363dbf15b Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Wed, 12 Feb 2014 14:59:37 -0300 Subject: [PATCH] [media] em28xx-dvb: fix PCTV 461e tuner I2C binding Add missing m88ts2022 module reference counts as removing that module is not allowed when it is used by em28xx-dvb module. That same module was not unregistered correctly, fix it too. Error cases validated by returning errors from m88ds3103, m88ts2022 and a8293 probe().
