drm: bridge: dw_hdmi: Fix constant truncation warning on phy_mask
In dw_hdmi_probe(), casting the bitwise complement of (HDMI_PHY_HPD |
HDMI_PHY_RX_SENSE) directly to u8 triggers a compiler warning
(-Wconstant-conversion).
Due to C integer promotion rules, the bitwise OR and bitwise NOT are
evaluated as 32-bit signed integers, producing 0xFFFFFF0D before being
cast down to u8.
Fix this by explicitly masking the inverted 32-bit result with 0xFF
to keep only the lower byte and prevent implicit upper-bit truncation.
