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

Applied to drm-misc-next tree (patch should show up in v5.9), thanks.

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.
