[PATCH] drm/fb-helper: Add force parameter to stub function

[PATCH] drm/fb-helper: Add force parameter to stub function

[Matt Coster]

The signature of drm_fb_helper_restore_fbdev_mode_unlocked() was modified
in commit 943240d342f14 ("drm/client: Pass force parameter to client
restore") to add a force parameter, but this was not added to the stub
equivalent for when CONFIG_DRM_FBDEV_EMULATION is not enabled.

The only caller depends on CONFIG_DRM_FBDEV_EMULATION, so the stub 
should never be called. If possible, remove it entirely.

Most of these stub functions are left overs from when fbdev emulation 
was less well isolated from the rest of DRM.

Best regards
