Subject: drm/panel: Provide convenience wrapper for .get_modes()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7bf93c73adb28d8db6b34c27d3edd96337a2d366;p=linux-beck.git

drm/panel: Provide convenience wrapper for .get_modes()

Add a convenience wrapper for the struct drm_panel_funcs' .get_modes()
function so that not every driver needs to check that the panel driver
implements the function before calling it.
