Subject: drm/msm: Remove local fbdev emulation Kconfig option
X-Git-Tag: firefly_0821_release~176^2~721^2~17^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a9ee34b70e07ce942806eda154e48ea3f754a76f;p=firefly-linux-kernel-4.4.55.git

drm/msm: Remove local fbdev emulation Kconfig option

DRM_MSM_FBDEV config is used to enable/disable fbdev emulation for the
msm kms driver.

Replace this with the top level DRM_FBDEV_EMULATION config option where
applicable. This also prevents build breaks caused by undefined
drm_fb_helper_* functions when legacy fbdev support was disabled.
