In the Linux kernel, the following vulnerability has been resolved:
mmc: dw_mmc-rockchip: Add missing private data for very old controllers
The really old controllers (rk2928, rk3066, rk3188) do not support UHS
speeds at all, and thus never handled phase data.
For that reason it never had a parse_dt callback and no driver private
data at all.
Commit ff6f0286c896 ("mmc: dw_mmc-rockchip: Add memory clock auto-gating
support") makes the private data sort of mandatory, because the init
function checks whether phases are configured internally or through the
clock controller.
This results in the old SoCs then experiencing NULL-pointer dereferences
when they try to access that private-data struct.
While we could have if (priv) conditionals in all places, it's way less
cluttery to just give the old types their private-data struct.
