Subject: [PATCH] [PATCH] pxafb: Minor driver fixes

Fixes for the pxafb driver:

* Return -EINVAL for resolutions that are too large as per framebuffer
  driver policy.

* Increase the error timeout for disabling the LCD controller.  The current
  timeout is sometimes too short on the Sharp Zaurus Cxx00 hardware and an
  extra delay in an error path shouldn't pose any problems.

* Fix a dev reference which causes a compile error when DEBUG is defined.
