From f41810921bdca37161a63f689cdcb36155f0fad6 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sat, 28 Dec 2019 23:26:14 +0100 Subject: [PATCH] mfd: dbx500-prcmu: Drop set_display_clocks() The display clocks are handled by the generic clock framework since ages, this code is completely unused and misleading. Delete it.
