From: Maarten Lankhorst Date: Tue, 11 Jul 2017 14:33:13 +0000 (+0200) Subject: drm/atomic: Add __must_check to drm_atomic_helper_swap_state. X-Git-Tag: android-x86-8.1-r1~2144^2~62^2~279 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=8a39374ef8b849dfd18e7d8dd52ef8ffee0f1042;p=android-x86%2Fkernel.git drm/atomic: Add __must_check to drm_atomic_helper_swap_state. Now that all drivers check the return value, convert swap_state to __must_check. This is done separately to force build warnings if we missed a driver.
