Ok, I applied all nine patches of Seqv3 patchseries.
If I try to compile I got
CHK include/config/kernel.release
make KBUILD_SRC=
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h
CHK include/generated/utsrelease.h
CHK include/generated/bounds.h
CHK include/generated/timeconst.h
CHK include/generated/asm-offsets.h
CALL scripts/checksyscalls.sh
CHK include/generated/compile.h
CHK kernel/config_data.h
CC drivers/gpu/drm/i915/i915_drv.o
In file included from drivers/gpu/drm/i915/i915_drv.c:34:0:
drivers/gpu/drm/i915/i915_drv.h:1706:23: error: field 'hotplug' has incomplete
type
struct i915_hotplug hotplug;
^
make[6]: *** [drivers/gpu/drm/i915/i915_drv.o] Error 1
So I commented this field out at the moment.
After reboot of this patched kernel, I have another error
[ 2.576428] [drm] GMBUS [i915 gmbus panel] timed out, falling back to bit
banging on pin 3
[ 2.586600] Loading compiled-in X.509 certificates
[ 2.588326] [drm:mipi_exec_i2c] *ERROR* i2c transfer failed -6
[ 2.588329] [drm:generic_exec_sequence] Starting MIPI sequence -
MIPI_SEQ_INIT_OTP
so black screen still exists here also with all patches applied.
I attach the whole dmesg
