From 40a55dc13e9dfa3a9575fd95633733554f4cde67 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Sun, 19 Jul 2020 11:38:34 +0200 Subject: drm/ingenic: Silence uninitialized-variable warning Silence compiler warning about used but uninitialized 'ipu_state' variable. In practice, the variable would never be used when uninitialized, but the compiler cannot know that 'priv->ipu_plane' will always be NULL if CONFIG_INGENIC_IPU is disabled. Silence the warning by initializing the value to NULL.
