[PATCH] ARM: Acornfb: Don't claim IRQ fbcon for cursor
The generic fbcon code tries to register and use the vsync IRQ for ARM platforms with acornfb, but forgets to disable its own cursor timer. The result is a flickering flashing cursor. Remove the code from the fbcon core to register this platform private interrupt. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
