This is a note to let you know that I've just added the patch titled MIPS: lantiq: add clk_round_rate() to the 4.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mips-lantiq-add-clk_round_rate.patch and it can be found in the queue-4.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 4e7d30dba493b60a80e9b590add1b4402265cc83 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens <hauke@xxxxxxxxxx> Date: Sun, 25 Oct 2015 23:21:42 +0100 Subject: MIPS: lantiq: add clk_round_rate() From: Hauke Mehrtens <hauke@xxxxxxxxxx> commit 4e7d30dba493b60a80e9b590add1b4402265cc83 upstream. This adds a basic implementation of clk_round_rate() The clk_round_rate() function is called by multiple drivers and subsystems now and the lantiq clk driver is supposed to export this, but doesn't do so, this causes linking problems like this one: ERROR: "clk_round_rate" [drivers/media/v4l2-core/videodev.ko] undefined!
