This is a note to let you know that I've just added the patch titled spi: bcm63xx-hsspi: Endianness fix for ARM based SoC to the 6.1-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: spi-bcm63xx-hsspi-endianness-fix-for-arm-based-soc.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit aca778056048ad947ce89d030e6e9f3ba0b503f7 Author: William Zhang <william.zhang@xxxxxxxxxxxx> Date: Mon Feb 6 22:58:17 2023 -0800 spi: bcm63xx-hsspi: Endianness fix for ARM based SoC [ Upstream commit 85a84a61699990db6a025b5073f337f49933a875 ] HSSPI controller uses big endian for the opcode in the message to the controller ping pong buffer. Use cpu_to_be16 to properly handle the endianness for both big and little endian host.
