In adv7511_probe, adv7511->hpd_work is bound with adv7511_hpd_work.
adv7511_irq_process might be called to start the work.
If we call adv7511_remove with an unfinished work. There may be a
race condition. Here is the possible sequence:

This chip supports controlling the backlight via DCS commands, on at
least some panels. Add support for doing so.
Note this may only concern the NT36523*W* variant. Nobody knows, really,
there's no docs.

Using 'port' instead of 'ports' for single-DSI usecases allows for saving
a couple of DTS LoC, including a level of indentation. Allow that.

Since you are resending this patch,
Currently, pkt_per_line is calculated by dividing slice_per_intf by
slice_count. This is incorrect, as slice_per_intf should be divided by
slice_per_pkt, which is not always equivalent to slice_count as it is
possible for there to be multiple soft slices per interface even though

hdisplay for compressed images should be calculated as bytes_per_slice *

Introduce MSM-specific DSC helper methods, as some calculations are

There are some overlap in calculations for MSM-specific DSC variables
between DP and DSI. In addition, the calculations for initial_scale_value

but aren't yet included in drm_dsc_helper.c.

Okay. Three cases, see below.
Your patch tries to fix the stride, but what if it's the _depth_
that's wrong ? Grub sets the mode, the pre-regression kernel picks this:
format=x8r8g8b8, mode=1024x768x32, linelength=4096

In between, I had tried CONFIG_SYSFB_SIMPLEFB=n . That "works", by
