Subject: iommu/amd: Remove duplicate checking code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ecef115d4540e3ef73551a21fb0622270a825110;p=linux-beck.git

iommu/amd: Remove duplicate checking code

amd_iommu_rlookup_table[devid] != NULL is already guaranteed
by check_device called before, it's fine to attach device at
this point.
