Thanks for going through all the backlog of patches in the fbdev area
every once in a while! That kind of housekeeping work is often
underappreciated, but rather important to keep the ship going.

Cheers, Daniel

PS: Of course also holds for everyone else doing this in other areas.
fbdev simply stuck out just now catching up on mails.

[PATCH] video: fbdev: pxafb: Use correct return value for pxafb_probe()

[Tiezhu Yang]

When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.
