Subject: KVM: Drop bogus x86_decode_insn() error check
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3e90943907ff84cf0379a57c01c296a9b33c903e;p=openwrt%2Fstaging%2Fblogic.git

KVM: Drop bogus x86_decode_insn() error check

x86_decode_insn() doesn't return X86EMUL_* values, so the check
for X86EMUL_PROPOGATE_FAULT will always fail.  There is a proper
check later on, so there is no need for a replacement for this
code.
