[PATCH v5 08/10] drm/rockchip: dw_hdmi_qp: Use local dev variable consistently in bind()

Cristian Ciocaltea
2026-04-26T00:20:49Z

Replace indirect struct device accesses via hdmi->dev and pdev->dev with
the local dev parameter already available in dw_hdmi_qp_rockchip_bind(),
for consistency and readability.
