Subject: [PATCH] HID: select NEW_LEDS for driver of Lenovo ThinkPad USB Keyboard with TrackPoint

commit 'HID: Driver for Lenovo Keyboard with Trackpoint'
(c1dcad2d32d0252e8a3023d20311b52a187ecda3) introduced a compiling error due to
unmetting dependency of CONFIG_LEDS_CLASS.

on i386:

ERROR: "led_brightness_set" [drivers/leds/led-class.ko] undefined!
ERROR: "leds_list" [drivers/leds/led-class.ko] undefined!
ERROR: "leds_list_lock" [drivers/leds/led-class.ko] undefined!

and possibly related:

warning: (ADB_PMU_LED && IWLWIFI && IWLEGACY && ATH5K && ATH9K && ATH9K_HTC && CARL9170_LEDS && TABLET_USB_WACOM && INPUT_WISTRON_BTNS && SENSORS_APPLESMC && IR_WINBOND_CIR && BACKLIGHT_ADP8860 && BACKLIGHT_ADP8870 && HID_LENOVO_TPKBD && ACER_WMI && ASUS_LAPTOP && DELL_LAPTOP && HP_ACCEL && THINKPAD_ACPI && EEEPC_LAPTOP && ASUS_WMI && ACPI_TOSHIBA && SAMSUNG_LAPTOP) selects LEDS_CLASS which has unmet direct dependencies (NEW_LEDS)
