Subject: km/ivm: fix string len check to support 7 char board names
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=62c9b9603e2552d6b39985738a957b51b0367e72;p=u-boot.git

km/ivm: fix string len check to support 7 char board names

The fanless boards now have a 7-digit (XXXXX-F) board name. This
triggers a border condition when reading this string in the IVM although
this string is smaller than the currenly read string size, but only by 1
character.

This patch corrects this by changing the size check condition for string
length. It is the same change that was done in the platform for this
same bug.
