[patch 1/8] m68k: Atari input drivers cleanup

[Geert Uytterhoeven]

[-- Attachment #1: atari-input-memleak-cleanup.diff --]
[-- Type: text/plain, Size: 6629 bytes --]

m68k: Atari input drivers cleanup:
  - memleak on failed init/register of input devices fixed
  - correct keycodes table (Atari keycodes are almost, but not entirely, equal 
    to Linux keycodes).
