Subject: Update print_buffer() to use const
X-Git-Tag: v2013.04-rc1~16^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bda32ffcf712806c7880ded25a012fbeede35e80;p=platform%2Fkernel%2Fu-boot.git

Update print_buffer() to use const

The buffer cannot be changed by this function, so change the buffer
pointer to a const. This allows callers with const pointer to use the
function without a cast.
