Subject: omap: Use resource_size
X-Git-Tag: v2.6.32-rc7~1^2~7
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=6d1352420901b0a74e6149a891ff4457f7199651;p=~shefty%2Frdma-dev.git

omap: Use resource_size

Use the resource_size function instead of manually calculating the
resource size. This reduces the chance of introducing off-by-one errors
and actually fixes one in mailbox.c.
