x86/wmi: delete unused wmi_data_lock mutex causing gcc warning
In commit bff431e49ff531a343fbb2b4426e313000844f32 ("ACPI: WMI: Add
ACPI-WMI mapping driver") this mutex was added, but the rest of the
final commit never actually made use of it, resulting in:
In file included from include/linux/mutex.h:29:0,
from include/linux/kernfs.h:13,
from include/linux/sysfs.h:15,
from include/linux/kobject.h:21,
from include/linux/device.h:17,
from drivers/platform/x86/wmi.c:35:
drivers/platform/x86/wmi.c:48:21: warning: ‘wmi_data_lock’ defined but not used [-Wunused-variable]
static DEFINE_MUTEX(wmi_data_lock);
^
A git grep shows no other instances/references to the wmi_data_lock.
Delete it, assuming that the mutex addition was just a leftover from
an earlier work in progress version of the change, since the original
dates from 2008.
