hwmon: (hp-wmi-sensors) Initialize pevents in hp_wmi_sensors_init()
The following warning is given by the Smatch static checker:
drivers/hwmon/hp-wmi-sensors.c:1937 hp_wmi_sensors_init()
error: uninitialized symbol 'pevents'.
If there are no instances of the HPBIOS_PlatformEvents WMI object
available, init_platform_events() never initializes this pointer,
which may then be passed to hp_wmi_debugfs_init() uninitialized.
The impact should be limited because hp_wmi_debugfs_init() uses this
pointer only if the count of HPBIOS_PlatformEvents instances is _not_
zero, while conversely, it will be uninitialized only if the count of
such instances _is_ zero. However, passing it uninitialized still
constitutes a bug.
