Box Date: Thu, 11 Apr 2024 02:58:48 +0000 (-0700) Subject: platform/x86/intel/sdsi: Set message size during writes X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7c277d4d16bac2e21ebb53e583d8db0b08cbdeb1;p=linux.git platform/x86/intel/sdsi: Set message size during writes New mailbox commands will support sending multi packet writes and updated firmware now requires that the message size be written for all commands along with the packet size. Since the driver doesn't perform writes larger than the packet size, set the message size to the same value. Signed-off-by: David E.
