[Mesa-dev] [PATCH] dri/kms: Always zero out struct drm_mode_create_dumb

2014-11-13 Thread Thierry Reding
From: Thierry Reding The DRM_IOCTL_MODE_CREATE_DUMB (and others) IOCTL isn't very rigorously specified, which has the effect that some kernel drivers do not consider the .pitch and .size fields of struct drm_mode_create_dumb outputs only. Instead they will use these as lower bounds and overwrite
