tools/power turbostat: decode MSR_MISC_FEATURE_CONTROL

Hello Len Brown,

The patch 33148d671cc1: "tools/power turbostat: decode MSR_MISC_FEATURE_CONTROL" from Jan 21, 2017, leads to the following static checker warning:

tools/power/x86/turbostat/turbostat.c:3918 decode_misc_feature_control()
warn: bitwise AND condition is false here

tools/power/x86/turbostat/turbostat.c
3908 void decode_misc_feature_control(void)
3909 {
3910 unsigned long long msr;
3911
3912 if (!has_misc_feature_control)
3913 return;
3914
3915 if (!get_msr(base_cpu, MSR_MISC_FEATURE_CONTROL, &msr))
3916 fprintf(outf, "cpu%d: MSR_MISC_FEATURE_CONTROL: 0x%08llx (%sL2-Prefetch %sL2-Prefetch-pair %sL1-Prefetch %sL1-IP-Prefetch)\n",
3917 base_cpu, msr,
3918 msr & (0 << 0) ? "No-" : "",

                                ^^^^^^^^^^^^^

Never true.

  3919                          msr & (1 << 0) ? "No-" : "",
  3920                          msr & (2 << 0) ? "No-" : "",
  3921                          msr & (3 << 0) ? "No-" : "");

Was this supposed to be 1 << 0, 1 << 2 etc?

3922 }
