[PATCH v2 0/4] fbdev: Make CONFIG_FB_DEVICE optional for drivers

[Chintan Patel]

This series makes CONFIG_FB_DEVICE optional for fbdev drivers that use
it only for sysfs interfaces, addressing Thomas Zimmermann’s TODO to
remove hard FB_DEVICE dependencies.

The series introduces a small helper, dev_of_fbinfo(), which returns
NULL when CONFIG_FB_DEVICE=n. This allows sysfs code paths to be skipped
via runtime checks, avoids #ifdef CONFIG_FB_DEVICE clutter, and keeps
full compile-time syntax checking.

Changes in v2:
Add dev_of_fbinfo() helper (suggested by Geert Uytterhoeven)
Replace #ifdef CONFIG_FB_DEVICE blocks with runtime NULL checks
Switch to fb_dbg() / fb_info() logging (suggested by Thomas Zimmermann)
