From: Colin Ian King <colin.k...@canonical.com>
Currently when the call to of_get_drm_display_mode fails the error return
path does not free an earlier allocated struct drm_display_mode, causing
a memory leak. Fix this by kfree'ing mode before returning.
Fixes: 76ecd9c9fb24 ("drm/imx: parallel-display: check return code from
of_get_drm_display_mode()")
