[PATCH 2/2] drm/msm/dsi/phy: rename DSI_PHY_7NM_QUIRK_PRE_V4_1 to DSI_PHY_7NM_QUIRK_V4_0

From: Pengyu Luo

Date: Thu Feb 26 2026 - 07:32:11 EST


The quirk flag DSI_PHY_7NM_QUIRK_PRE_V4_1 is renamed to
DSI_PHY_7NM_QUIRK_V4_0 to better reflect the actual hardware revision
it applies to. (Only SM8150 uses it, its hardware revision is 4.0)

No functional change.
