Summary
perf/x86/intel/uncore: Fix reference count leak in hswep_has_limit_sbox()
Details

In the Linux kernel, the following vulnerability has been resolved:

perf/x86/intel/uncore: Fix reference count leak in hswephaslimit_sbox()

pcigetdevice() will increase the reference count for the returned 'dev'. We need to call pcidevput() to decrease the reference count. Since 'dev' is only used in pcireadconfigdword(), let's add pcidev_put() right after it.
