Re: [PATCH 4/4] drm: pl111: Update documentation

[Emil Velikov <emil.l.velikov@gmail.com>]

Hi all,

Inspired by Linus and my personal confusion with the report, allow me
to put some suggestions. Followed by an illustrative example.

One thing which was always inclear me - is the warning identical in
all the branches listed.

Reference to the manual tends to be better than an old SO thread.

Please do not list old warnings/errors. They only distract and dilute
what/where the problem is.

All of this seems useful when debugging the kernel test robot itself.
Which in this case is misleading as hell.


Here is something which is much shorter, with clearer structure and
reads much easier.

Hi Linus,

This is an automated message from your friendly test robot.
We've noticed some issues with your patch although being a robot,
kindly double-check the results.

Branches:
[if the warning/errors are the same group them, otherwise split them
in separate sections]

- drm-exynos/exynos-drm-next [1]: WARNING
- drm-intel/for-linux-next [2]: WARNING
- .... : WARNING
drivers/gpu/drm/pl111/pl111_drv.c:1: warning: 'ARM PrimeCell PL111
CLCD Driver' not found
- tegra-drm/drm/tegra/for-next [3]: WARNING
some other warning
- drm-tip/drm-tip [4] drm/drm-next [5]: cannot apply series

Note: when submitting patches, please use `--base` as documented in
https://git-scm.com/docs/git-format-patch.


To reproduce:
 - wget https://url/to/build/toolchain // when applicable
 - wget https://url/to/config // when applicable
 - make htmldocs // use explicit make command instead of magic shell
script, as seen in the cross build reports


If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <lkp@intel.com>

Thank you
