    x86/wmi: delete unused wmi_data_lock mutex causing gcc warning · f62a4ffd
    Paul Gortmaker authored
    In commit bff431e4
     ("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.
