From 7c277d4d16bac2e21ebb53e583d8db0b08cbdeb1 Mon Sep 17 00:00:00 2001 From: "David E. Box" Date: Wed, 10 Apr 2024 19:58:48 -0700 Subject: platform/x86/intel/sdsi: Set message size during writes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
