torvalds · torvalds · commit be129fab66f2 · 2022-06-26T09:13:51.000-07:00
Pull fbdev fixes from Helge Deller:
 "Two bug fixes for the pxa3xx and intelfb drivers:

   - pxa3xx-gcu: Fix integer overflow in pxa3xx_gcu_write

   - intelfb: Initialize value of stolen size

  The other changes are small cleanups, simplifications and
  documentation updates to the cirrusfb, skeletonfb, omapfb,
  intelfb, au1100fb and simplefb drivers"
