From: Dmitry Baryshkov Date: Wed, 9 Jun 2021 21:12:11 +0000 (+0300) Subject: drm/msm/dsi: do not enable PHYs when called for the slave DSI interface X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a14440042fe8dac6b7c507a946f46a6f50c9c05d;p=linux.git drm/msm/dsi: do not enable PHYs when called for the slave DSI interface Move the call to dsi_mgr_phy_enable after checking whether the DSI interface is slave, so that PHY enablement happens together with the host enablement.
