Subject: x86/decoder: Use stderr if insn sanity test fails
X-Git-Tag: v4.10-rc1~185^2~15
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bb12d6740f6de393927362f23f833a79d85df384;p=karo-tx-linux.git

x86/decoder: Use stderr if insn sanity test fails

If the instruction sanity test fails, it prints a "Failure" message to
stdout. Make this program behave like the rest of the build and print
that message to stderr.
