Subject: [RFC 1/8] drm/msm/dsi: make msm_dsi_phy_pll_restore_state static function
Date: Sat, 29 May 2021 03:25:01 +0300	[thread overview]
Message-ID: <20210529002508.3839467-2-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210529002508.3839467-1-dmitry.baryshkov@linaro.org>

msm_dsi_phy_pll_restore_state() is only called from msm_dsi_phy_enable(),
so there is no need to export it. Mark it static.
