Subject: [PATCH] drm/i915: Fix using BIT_ULL() vs. BIT() for power domain masks
Git-commit: 6389902072db658366ec53711a83d711364b7330
Patch-mainline: v4.16-rc1
References: FATE#322643 bsc#1055900
No-fix: 17bd6e66d8f677b1b250d098097fbed6e70175ef
The power domain masks are 64 bit wide, so we need BIT_ULL() when
setting bits in them, these ones were missed during converting from 32
to 64 bit masks. All 3 enums are <32 atm, so this didn't cause a real
problem.
Fixes: d8fc70b7367b ("drm/i915: Make power domain masks 64 bit long")
