[GIT PULL] fbdev updates for v6.15-rc1

[Helge Deller]

Hi Linus,

please pull some updates regarding fbdev for 6.15-rc1:

The fbcon packed pixel drawing routines have been refactored to bring the
implementations for system and I/O memory in sync.  The other patches add some
parameter checks, static attribute groups for sysfs entries and console fixes.

Thanks,
Helge

  fbdev: fsl-diu-fb: add missing device_remove_file() (2025-03-26 22:39:21 +0100)

----------------------------------------------------------------
fbdev fixes and updates for 6.15-rc1:

This includes a major refactoring of the fbcon packed pixel drawing routines,
contributed by Zsolt Kajtar.  The original version duplicated more or less the
same algorithms for both system and i/o memory.  The new implementation is more
robust, both implementations are now feature complete (e.g. pixel order
reversing now supported by both), behaves the same way as it uses the identical
code for both variants and adds support for foreign endian framebuffers.

The other fixes and cleanups are:
- dummycon: only build module if there are users and fix rows/cols (Arnd Bergmann)
- mdacon: rework dependency list (Arnd Bergmann)
- lcdcfb, fsl-diu-fb, fbcon: Fix registering and removing of sysfs (Shixiong Ou)
- sm501fb: Add some geometry checks (Danila Chernetsov)
- omapfb: Remove unused code, add value checks (Leonid Arapov)
- au1100fb: Clean up variable assignment (Markus Elfring)
- pxafb: use devm_kmemdup*()  (Raag Jadav)
