      video: Fix the HGA framebuffer driver · 529ed806
      由 Brent Cook 提交于 
      Resurrected some old hardware and fixed up the hgafb driver to work
again. Only tested with fbcon, since most fbdev-based software appears
to only support 12bpp and up. It does not appear that this driver has
worked for at least the entire 2.6.x series, perhaps since 2002.

Hercules graphics hardware uses packed pixels horizontally, but rows are
not linear. In other words, the pixels are not packed vertically. This
means that custom imageblit, fillrect and copyarea need to be written
specific to the hardware.

 * Removed the experimental acceleration option, since it is required
   for the hardware to work.
 * Fixed imageblit to work with fb_image's wider than 8 pixels.
 * Updated configuration text (HGA hardware is from 1984)

      drivers/video/carminefb.c: improve error handling · e045da7d
      由 Julia Lawall 提交于 
      This code had an error handling goto to the wrong place, a misplaced
release_mem_region, and a duplicated release_mem_region.

The semantic match that finds the double release_mem_region is as follows:

// <smpl>

release_mem_region(e1, e2)@p2;

@@
expression e <= r.e1,e3;
expression r.e1,e2;

      fbdev: sh_mobile_lcdcfb: Enable 32 bpp and 24 bpp support · 417d4827
      由 Magnus Damm 提交于 
      This patch extends the LCDC driver with 24 bpp
and 32 bpp support.

These modes have been kept disabled earlier due
to dependencies between the potential two LCDC
channels that are exported as two separate
framebuffer devices. The dependency boils down
to a byte swap register that is shared between
multiple channels.

With this patch applied all single channel LCDC
hardware can chose freely from 16, 24 and 32 bpp.
Dual channel LCDC must stick to the same setup
for both channels.

Without this patch only 16 bpp is fully supported.
