Subject: drivers/block/mg_disk.c: use resource_size()
X-Git-Tag: v2.6.33-rc3~40^2~5
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e019ef0c4f11a0acb79b89fb1e09c72197b42bbe;p=karo-tx-linux.git

drivers/block/mg_disk.c: use resource_size()

Use resource_size() for ioremap.

The ioremap appears to be passing the incorrect size for the platform
resource.  Unfortunately, I can't locate a user in mainline to verify
this.  Using resource_size should be the correct fix.
