Subject: crypto: ccp - Remove check for x86 family and model
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3f19ce2054541a6c663c8a5fcf52e7baa1c6c5f5;p=openwrt%2Fstaging%2Fblogic.git

crypto: ccp - Remove check for x86 family and model

Each x86 SoC will make use of a unique PCI ID for the CCP
device so it is not necessary to check for the CPU family
and model.
