Subject: viafb: restore display on resume
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b75f2c01de34daf0b25cbd75fcf00511548ffa1e;p=linux-beck.git

viafb: restore display on resume

This patch makes viafb restore the display on resume by calling
viafb_set_par. Resumeing has still its issues:
- will probably freeze most machines (for me on VX800 reliable on the
  second resume)
- under some configurations the screen appears on the wrong output
  device (reason unknown)
