Subject: drm/i915: Skip FDI vs. dotclock sanity check during readout
MIME-Version: 1.0

Git-commit: c9ae7b866f32043d23a34d00a5e6e8d86d2cf10e
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
The VBIOS/GOP may not program the FDI M/n vs. dotclock entirely
consistently. Eg. on a SNB Thinkpad X220 LVDS I see dotclock of
69.286 MHz (the best the DPLL can do) vs. FDI M/N 69.3 MHz
(matches what the EDID actually declares).
