[CPUFREQ] pcc-cpufreq: don't load driver if get_freq fails during init. Return 0 on failure. This will cause the initialization of the driver to fail and prevent the driver from loading if the BIOS cannot handle the PCC interface command to "get frequency". Otherwise, the driver will load and display a very high value like "4294967274" (which is actually -EINVAL) for frequency: # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 4294967274 Signed-off-by: Naga Chumbalkar <nagananda.chumbalkar@hp.com> CC: stable@kernel.org Signed-off-by: Dave Jones <davej@redhat.com>
