Subject: lmb: correct size of the regions array
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=cb1e619824f0c942ccd9b230b5f41caaf7cd91b4;p=u-boot.git

lmb: correct size of the regions array

As in lmb_region, cnt < max and in the lmb library
use region[i] only with i in 0...cnt, this region array size
can be reduced by 1 element without overflow.

This patch allows to reduce the struct lmb size.
