When building with -Wsometimes-uninitialized, Clang warns: arch/powerpc/xmon/ppc-dis.c:157:7: warning: variable 'opcode' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] if (cpu_has_feature(CPU_FTRS_POWER9)) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ arch/powerpc/xmon/ppc-dis.c:167:7: note: uninitialized use occurs here if (opcode == NULL) ^~~~~~ arch/powerpc/xmon/ppc-dis.c:157:3: note: remove the 'if' if its condition is always true if (cpu_has_feature(CPU_FTRS_POWER9)) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ arch/powerpc/xmon/ppc-dis.c:132:38: note: initialize the variable 'opcode' to silence this warning const struct powerpc_opcode *opcode; ^ = NULL 1 warning generated. This warning seems to make no sense on the surface because opcode is set to NULL right below this statement. However, there is a comma instead of semicolon to end the dialect assignment, meaning that the opcode assignment only happens in the if statement. Properly terminate that line so that Clang no longer warns. Fixes: 5b102782 ("powerpc/xmon: Enable disassembly files (compilation changes)") Signed-off-by:
