Subject: amd-xgbe: Resolve checkpatch warning about sscanf usage
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=66f95c35c413f674a835034dc667099b44225df2;p=linux-beck.git

amd-xgbe: Resolve checkpatch warning about sscanf usage

Checkpatch issued a warning preferring to use kstrto<type> when
using a single variable sscanf.  Change the sscanf invocation to
a kstrtouint call.
