Subject: [PATCH 01/17] plaform: chrome: Add PL_CHROMEOS export symbol namespace
Date:   Wed,  5 Jan 2022 14:06:37 -0800
Message-Id: <20220105220653.122451-2-gwendal@chromium.org>

Add PL_CHROMEOS to hold functions exposed by the platform chromeos
subsystem:

for i in EXPORT_SYMBOL_GPL EXPORT_SYMBOL; do
  sed -i "s/$i(\([^)]*\)/$i_NS(\1, PL_CHROMEOS/"
    $(grep -lr $i drivers/platform/chrome/)
done
