From: Hans Verkuil Date: Tue, 29 Jan 2013 16:16:06 +0000 (-0300) Subject: [media] cx231xx-417: share ioctls with cx231xx-video X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b86d15440b683f8634c0cb26fc0861a5bc4913ac;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [media] cx231xx-417: share ioctls with cx231xx-video Share tuner, frequency, debug and input ioctls with cx231xx-video. These are all shared resources, so no need to implement them again.
