Thanks. I will also apply this patch on top, otherwise we'll be corrupting
memory in steelseries_srws1_probe() here:
drv_data->led[SRWS1_NUMBER_LEDS] = led;
From: Jiri Kosina <[email protected]>
Subject: [PATCH] HID: steelseries: fix out of bound array access
The last field of the driver_data->leds[] array is used to store the
special toggle for setting all leds simultaneously, so we need to allocate
appropriate number of led_classdev pointers.
