[ Upstream commite397c56429] hotkey_exit() already takes the mutex around the hotkey_poll_stop_sync() call, but not around the other calls. commit38831eaf7d("platform/x86: thinkpad_acpi: use lockdep annotations") has added lockdep_assert_held() checks to various hotkey functions. These lockdep_assert_held() checks fail causing WARN() backtraces in dmesg due to missing locking in hotkey_exit(), fix this.
