This is a note to let you know that I've just added the patch titled clk: meson: clk-pll: propagate the error from meson_clk_pll_set_rate() to the 5.11-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: clk-meson-clk-pll-propagate-the-error-from-meson_clk.patch and it can be found in the queue-5.11 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 6922e516a39d2449a00e9a995aa99de6db65a182 Author: Martin Blumenstingl <martin.blumenstingl@xxxxxxxxxxxxxx> Date: Sat Dec 26 13:15:56 2020 +0100 clk: meson: clk-pll: propagate the error from meson_clk_pll_set_rate() [ Upstream commit ccdc1f0836f8e37b558a424f1e491f929b2e7ede ] Popagate the error code from meson_clk_pll_set_rate() when the PLL does not lock with the new settings.
