fbdev fixes and updates for kernel v5.20-rc1
The two major changes in this patchset corrects VGA modes, color handling and various other smaller fixes in the Atari framebuffer (by Geert Uytterhoeven), and devm_* conversion, platform data fixes and header cleanups in the imxfb driver (by Uwe Kleine-König). Other small patches clean up code in sa1100fb, cirrusfb and omapfb, fix a refcount leak in amba-clcd (by Liang He), and adds parameter checks to arkfb, i740fb, vt8623fb and s3fb (by Zheyu Ma). -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQS86RI+GtKfB8BJu973ErUQojoPXwUCYu7IyAAKCRD3ErUQojoP X2jtAP961tA3uP7AdRkQj5jXzChAsDajkrA9vBf3Ihn1M73SHwEA/A6JOgPQAlp6 NGIwUlHEUikgylU9da2C0jzesstmJwU= =+7rt -----END PGP SIGNATURE----- Merge tag 'for-5.20/fbdev-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev Pull fbdev updates from Helge Deller: "The two major changes in this patchset corrects VGA modes, color handling and various other smaller fixes in the Atari framebuffer (by Geert Uytterhoeven), and devm_* conversion, platform data fixes and header cleanups in the imxfb driver (by Uwe Kleine-König).
