From: Devin Heitmueller Date: Wed, 11 Mar 2009 05:58:53 +0000 (-0300) Subject: V4L/DVB (11059): xc5000: fix bug for hybrid xc5000 devices with IF other than 5380 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ea2278633ab4728c41b4043f47df4d3e39131992;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git V4L/DVB (11059): xc5000: fix bug for hybrid xc5000 devices with IF other than 5380 The xc5000 driver has a bug where the IF is always set to whatever the first caller to dvb_attach() provides. This fails when the device requires an IF other than 5380 and the analog driver is loaded first through tuner-core (which always supplies the hard-coded value of 5380). Thanks to Michael Krufky and Steven Toth for providing sample hardware, engineering level support, and testing.
