CVE-2022-50318: perf/x86/intel/uncore: Fix reference count leak in hswep_has_limit_sbox()
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/intel/uncore: Fix reference count leak in hswephaslimitsbox()
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 pcidevput() right after it.
