After commit c104c16073b7 ("Kunit to check the longest symbol length"), there is a warning when building with clang because there is now a definition of unlikely from compiler.h in tools/include/linux, which conflicts with the one in the instruction decoder selftest: arch/x86/tools/insn_decoder_test.c:15:9: warning: 'unlikely' macro redefined [-Wmacro-redefined] Remove the second unlikely() definition, as it is no longer necessary, clearing up the warning.
