From: Hans Verkuil Date: Sat, 20 Sep 2014 10:36:39 +0000 (-0300) Subject: [media] adv7604/adv7842: fix il_vbackporch typo and zero the struct X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f8789e6d9c824aeaeeb5b44b926dc8e960487cfe;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [media] adv7604/adv7842: fix il_vbackporch typo and zero the struct Both adv7604 and adv7842 had the same typo in the code that sets the vertical backporch for the second interlaced field: it was assigned to vbackporch instead of il_vbackporch. In addition, the timings struct wasn't zeroed in the adv7842 driver, leaving several fields to undefined values causing the timing match function to fail.
