Subject: [PATCH 2/3] platform/chrome: cros_ec_proto: Rename cros_ec_command function
Date:   Mon,  6 Jun 2022 20:18:03 +0000
Message-Id: <20220606201825.763788-3-pmalani@chromium.org>
In-Reply-To: <20220606201825.763788-1-pmalani@chromium.org>

cros_ec_command() is the name of a function as well as a struct, as such
it can confuse indexing tools (like ctags). Avoid this by renaming it to
cros_ec_cmd(). Update all the callsites to use the new name.

This patch is a find-and-replace, so should not introduce any functional
changes.
