thermal/intel_powerclamp: Remove set-but-not-used variables
In poll_pkg_cstate() function, the variables jiffies_last and jiffies_now are set but never used. This has been detected by building the driver with W=1: drivers/thermal/intel_powerclamp.c: In function ‘poll_pkg_cstate’: drivers/thermal/intel_powerclamp.c:464:23: warning: variable ‘jiffies_last’ set but not used [-Wunused-but-set-variable] static unsigned long jiffies_last; ^ Signed-off-by: Augusto Mecking Caringi <augustocaringi@gmail.com> Acked-by: Jacob Pan <jacob.jun.pan@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
