Subject: [PATCH 3/5] platform/chrome: cros_ec_proto: Make data pointers void
Date:   Wed, 29 Sep 2021 19:23:52 -0700
Message-Id: <20210930022403.3358070-4-pmalani@chromium.org>

Convert the input and output data pointers for cros_ec_command() to
void pointers so that the callers don't have to cast their custom
structs to uint8_t *.
