From d490c9cd2f67399e1dbc951f190d03724b81d0c8 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 29 Jun 2017 14:49:59 +0530 Subject: [PATCH] drm/msm/mdp5: Fix compilation warnings Following compilation warnings were observed for these files: CC [M] drivers/gpu/drm/msm/mdp/mdp5/mdp5_mdss.o drivers/gpu/drm/msm/mdp/mdp5/mdp5_crtc.c: In function 'blend_setup': drivers/gpu/drm/msm/mdp/mdp5/mdp5_crtc.c:223:7: warning: missing braces around initializer [-Wmissing-braces] enum mdp5_pipe stage[STAGE_MAX + 1][MAX_PIPE_STAGE] = { SSPP_NONE }; ^ drivers/gpu/drm/msm/mdp/mdp5/mdp5_crtc.c:223:7: warning: (near initialization for 'stage[0]') [-Wmissing-braces] drivers/gpu/drm/msm/mdp/mdp5/mdp5_crtc.c:224:7: warning: missing braces around initializer [-Wmissing-braces] enum mdp5_pipe r_stage[STAGE_MAX + 1][MAX_PIPE_STAGE] = { SSPP_NONE }; ^ drivers/gpu/drm/msm/mdp/mdp5/mdp5_crtc.c:224:7: warning: (near initialization for 'r_stage[0]') [-Wmissing-braces] drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c: In function 'mdp5_plane_mode_set': drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c:892:9: warning: missing braces around initializer [-Wmissing-braces] struct phase_step step = { 0 }; ^ drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c:892:9: warning: (near initialization for 'step.x') [-Wmissing-braces] drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c:893:9: warning: missing braces around initializer [-Wmissing-braces] struct pixel_ext pe = { 0 }; ^ drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c:893:9: warning: (near initialization for 'pe.left') [-Wmissing-braces] This happens because in the first case we were initializing a two dimensional array with {0} and in the second case we were initializing a struct containing two arrays with {0}. Fix them by adding another pair of {}.
