Subject: viafb: Unmap the frame buffer on initialization error
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1b1f8cd299d3c5a90c2ec1c24c271a0b536e5891;p=linux-beck.git

viafb: Unmap the frame buffer on initialization error

This was part of Harald's "make viafb a first-class citizen using
pci_driver" patch, but somehow got dropped when that patch went into
mainline.
