Subject: pxa168fb: fix incorrect resource calculation
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e3396b263c6a8f086a99f1d524272ff409d66de0;p=openwrt%2Fstaging%2Fblogic.git

pxa168fb: fix incorrect resource calculation

The size calculation is not correct.  It should be end - start + 1.
Use resource_size() to caculate it.
