x86: PM: Make APM idle driver initialize polling state
Update the APM driver overlooked by commit 1b39e3f813b4 (cpuidle: Make drivers initialize polling state) to initialize the polling state like the other cpuidle drivers modified by that commit to prevent cpuidle from crashing. Fixes: 1b39e3f813b4 (cpuidle: Make drivers initialize polling state) Reported-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Tested-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: 4.14+ <stable@vger.kernel.org> # 4.14+ Signed-off-by: Rafael J.
