From: Ben Hutchings Date: Sun, 19 Aug 2012 22:32:27 +0000 (-0300) Subject: media: rc: ite-cir: Initialise ite_dev::rdev earlier X-Git-Tag: v3.5.7~125 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ec50ab936cd482309eec4917e627db4a86b4c762;p=karo-tx-linux.git media: rc: ite-cir: Initialise ite_dev::rdev earlier commit 4b961180ef275035b1538317ffd0e21e80e63e77 upstream. ite_dev::rdev is currently initialised in ite_probe() after rc_register_device() returns. If a newly registered device is opened quickly enough, we may enable interrupts and try to use ite_dev::rdev before it has been initialised. Move it up to the earliest point we can, right after calling rc_allocate_device().
