fbdev fixes and updates for kernel v5.18-rc1
Lots of small fixes and code cleanups across most of the fbdev drivers. This includes conversions to use helper functions, const conversions, spelling fixes, help text updates, adding return value checks, small build fixes, and much more. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQS86RI+GtKfB8BJu973ErUQojoPXwUCYjogFQAKCRD3ErUQojoP X3Y7AQD/0Qd0zm6klv4EPeyLXOYzs6uXdyHiJGyCBABP3WxKZQD+J4yNXjd1g50A iGbsawaUpFMcaXTETr0NcrtRkc5jCgY= =HHa3 -----END PGP SIGNATURE----- Merge tag 'for-5.18/fbdev-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev Pull fbdev updates from Helge Deller: "Lots of small fixes and code cleanups across most of the fbdev drivers.
