arch/x86/kernel/msr_whitelist.c:200:18-19: WARNING comparing pointer to 0 arch/x86/kernel/msr_whitelist.c:203:27-28: WARNING comparing pointer to 0
Compare pointer-typed values to NULL rather than 0
Semantic patch information: This makes an effort to choose between !x and x == NULL. !x is used if it has previously been used with the function used to initialize x. This relies on type information. More type information can be obtained using the option -all_includes and the option -I to specify an include path.
