[Linux-fbdev-devel] [PATCH 2/6] vesafb: Change return error id

[Antonino A. D. <ad...@ho...>]

From: <Stuart_Hayes@Dell.com>

  I'm getting a message in dmesg:  "localhost kernel: vesafb: probe of
  vesafb0 failed with error -6"

  I searched the web, and found that a lot of people are getting this, but
  I couldn't find an answer, so I looked into it.

  This appears to be because "vesafb" returns -ENXIO ("No such device or
  address") when its probe function fails.  However, driverse/base/bus.c
  spews an error message during device_attach() if a matching driver's
  probe function returns anything but -ENODEV ("No such device").
