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.
