This is a note to let you know that I've just added the patch titled firmware: arm_scmi: Fix sorting of retrieved clock rates to the 5.15-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: firmware-arm_scmi-fix-sorting-of-retrieved-clock-rat.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 57a7f7ae63424f35976dcc9a2566ecb7b299b98a Author: Cristian Marussi <cristian.marussi@xxxxxxx> Date: Fri Mar 18 09:28:13 2022 +0000 firmware: arm_scmi: Fix sorting of retrieved clock rates [ Upstream commit 23274739a5b6166f74d8d9cb5243d7bf6b46aab9 ] During SCMI Clock protocol initialization, after having retrieved from the SCMI platform all the available discrete rates for a specific clock, the clock rates array is sorted, unfortunately using a pointer to its end as a base instead of its start, so that sorting does not work. Fix invocation of sort() passing as base a pointer to the start of the retrieved clock rates array.
