Thanks for your patch. I have tested it on LNL platform, it works fine.
Please fix the build warning reported by kernel test robot. https://lore.kernel.org/oe-kbuild-all/202406011319.hk4MAysc-lkp@xxxxxxxxx/
drivers/hid/intel-ish-hid/ishtp/loader.c:170: warning: Function parameter or struct member 'fragment_count' not described in 'prepare_dma_bufs'
After that, please add my name.
