6.6-stable review patch. If anyone has any objections, please let me know.

From: Arnd Bergmann <arnd@xxxxxxxx>
[ Upstream commit 924d66011f2401a4145e2e814842c5c4572e439f ]
The PHY portion of the mediatek hdmi driver was originally part of
the driver it self and later split out into drivers/phy, which a
'select' to keep the prior behavior.
However, this leads to build failures when the PHY driver cannot
be built:
WARNING: unmet direct dependencies detected for PHY_MTK_HDMI
Depends on [n]: (ARCH_MEDIATEK || COMPILE_TEST [=y]) && COMMON_CLK [=y] && OF [=y] && REGULATOR [=n]
Selected by [m]:
- DRM_MEDIATEK_HDMI [=m] && HAS_IOMEM [=y] && DRM [=m] && DRM_MEDIATEK [=m]
ERROR: modpost: "devm_regulator_register" [drivers/phy/mediatek/phy-mtk-hdmi-drv.ko] undefined!
ERROR: modpost: "rdev_get_drvdata" [drivers/phy/mediatek/phy-mtk-hdmi-drv.ko] undefined!
The best option here is to just not select the phy driver and leave that
up to the defconfig. Do the same for the other PHY and memory drivers
selected here as well for consistency.
