Patch submission preferences: request_mem_region changes in fbdev drivers

Hello Thomas,

I'm preparing patches to add proper memory-region requests across legacy 
fbdev drivers (use of 
request_mem_region/pci_request_region/devm_request_mem_region where 
appropriate) to avoid conflicts between fbdev and DRM drivers. I’ve 
started making changes (examples: pvr2fb.c, macfb.c, cyber2000fb.c, 
xilinxfb.c).

Before I prepare a patch series, could you please advise:

Preferred format: a single combined patch or a series of smaller 
patches? If a series, do you prefer one patch per driver file, per 
driver family, or grouped another way?
Any drivers or areas to exclude or treat specially (e.g., vga16fb or 
VGA-exclusive ranges)?
Any tests or checks you expect before posting (build, boot smoke tests, 
Kconfig options to verify)?
I can prepare an initial series and send it for review; I’ll follow your 
preferred format. Thanks for guidance.

Thank you,
Chintan Patel
