From 2f3dd39e2b492bec366487a2c9bcbdbd7792f77c Mon Sep 17 00:00:00 2001 From: Stephen Boyd <swboyd@chromium.org> Date: Mon, 2 Oct 2023 17:34:28 -0700 Subject: [PATCH] platform/chrome: cros_ec_proto: Mark outdata as const The 'outdata' is copied to the data buffer in cros_ec_cmd() before being sent over to the EC. Mark the argument as const so that callers can pass const pointers to this function and so that callers know the data won't be modified.
