The filename of the patch is: clk-at91-peripheral-fix-return-value.patch and it can be found in the queue-6.17 subdirectory.

If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

clk: at91: peripheral: fix return value

[ Upstream commit 47b13635dabc14f1c2fdcaa5468b47ddadbdd1b5 ] determine_rate() is expected to return an error code, or 0 on success. clk_sam9x5_peripheral_determine_rate() has a branch that returns the parent rate on a certain case. This is the behavior of round_rate(), so let's go ahead and fix this by setting req->rate.

Please don't backport any of my round_rate() to determine_rate() migrations to the stable kernels. I have maybe close to 200 of these patches for various clk drivers, and stable can stay on round_rate(). There's no functional change.

Stephen mentioned this work on his pull to Linus about how this is all prerequisite work to get to the real task of improving the clk rate setting process. https://lore.kernel.org/linux-clk/20251007051720.11386-1-sboyd@kernel.org/
