Subject: mach-snapdragon: Fix overwriting last digit of serial number
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=740370282e0caa9fab1c5865fe9b9a58ac008c5f;p=u-boot.git

mach-snapdragon: Fix overwriting last digit of serial number

When generating the MAC address based on the boards serial number
the last digit was overwritten with the null termination. That way
boards with serial numbers close to each other would use the same
MAC address.
