Subject: [PATCH 03/10] ARM: OMAP1: ams-delta: Supersede custom led device by leds-gpio
Now that the Amstrad Delta on-board latches have been converted to GPIO
devices, use the generic driver to control on-board LEDs which hang off
those latches.
Depends on patch 2/10 "ARM: OMAP1: Convert Amstrad E3 latches to
basic_mmio_gpio".
