From: Andrzej Hajda Date: Mon, 17 Nov 2014 08:54:19 +0000 (+0100) Subject: drm/exynos/fimd: stop using manager->ctx pointer X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=400c8ac8fc78f51dc7eb187dcf2320fb616c8215;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/exynos/fimd: stop using manager->ctx pointer The patch replaces accesses to manager->ctx pointer by container_of construct. As fimd was the last user of ctx the patch removes this field as well.
