Subject: crypto: mv_cesa - Use resource_size
X-Git-Tag: v2.6.35-rc1~446^2~17
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=5bdd5ded95b3188d58ba43ac801b8849cbea1b16;p=linux.git

crypto: mv_cesa - 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.
