Update the Atmel HLCDC code to use DRM print macros drm_*() instead of
dev_warn() and dev_err(). This change ensures consistency with DRM
subsystem logging conventions [1].

v3:
* include header file to fix compilation. Thanks Manikandan.
v2:
* replace dev_dbg with drm_dbg in atmel_hlcdc_plane.c
* https://lore.kernel.org/all/20250806183049.52112-2-eslam.medhat1993@gmail.com/

2.43.0Hi Eslam Khafagy,
The patch appears to have been sent with spaces in place of
tabs in the diff, which breaks kernel coding style [1] and makes it fail
to apply.
Please ensure your editor is configured to use tabs for indentation and
use `git send-email` or b4 directly, not via an email client that may
alter whitespace.
Could you please run checkpatch.sh and fix any reported errors or
warnings before submitting the patch?

Thank you for the feedback.
But i have rechecked the patch. I don't seem to have altered any tabs
with spaces.

checkpatch.sh only reports two warnings:
WARNING: 'funtions' may be misspelled - perhaps 'functions'?
#78:
Subject: [PATCH v3] drm: atmel-hlcdc: replace dev_* print funtions with drm_* variants
^^^^^^^^
WARNING: Prefer a maximum 75 chars per line (possible unwrapped commit description?)
#95:
https://docs.kernel.org/gpu/todo.html#convert-logging-to-drm-functions-with-drm-device-parameter
but no errors regarding tabs or spaces.
I'll fix the first one in v4. can you confirm indeed i have not altered tabs with spaces first?

The patch downloaded directly from https://lore.kernel.org/ applies
without issues.
It’s likely the version saved from my mail client (Thunderbird) is
