This is a note to let you know that I've just added the patch titled interconnect: qcom: bcm-voter: Use enable_maks for keepalive voting to the 6.5-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: interconnect-qcom-bcm-voter-use-enable_maks-for-keep.patch and it can be found in the queue-6.5 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit f354d92f925943932108ab879dc284b443a91ad2 Author: Konrad Dybcio <konrad.dybcio@xxxxxxxxxx> Date: Sat Aug 12 01:16:16 2023 +0200 interconnect: qcom: bcm-voter: Use enable_maks for keepalive voting [ Upstream commit 1a70ca71547be051769f0628aa09717694f508f0 ] BCMs with an enable_mask expect to only have that specific value written to them. The current implementation only works by miracle for BCMs with enable mask == BIT(0), as the minimal vote we've been using so far just so happens to be equal to that. Use the correct value with keepalive voting.
