Hi dri-devel,
what is the difference between GTT and GART for AMD GPUs?
From what I gathered when looking through the mailing list archives and
the freedesktop docs [1] as well as wikipedia [2],
these terms seem to be synonymous, but that can not be the whole truth

NO_IRQ is used to check the return of irq_of_parse_and_map().
On some architecture NO_IRQ is 0, on other architectures it is -1.
irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ.
So use 0 instead of using NO_IRQ.

This patch series adds proper support for the panel used in OnePlus 6T
smartphones (s6e3fc2x01). Previously, the panel relied on the driver
used by the sofef00 panel which failed to properly initialise it after
a reset.

drm/msm capitalizes hex numbers rather randomly. Try to unify it.

I could not find any strict hex capitalization rules for Linux, so
I'm sending this very loosely, without

A duplicated line 'select DRM_KMS_HELPER' was introduced in Kconfig file
by commit 09717af7d13d ("drm: Remove CONFIG_DRM_KMS_CMA_HELPER option"),
so remove it.
