[PATCH 4/4] ARM: s3c: crag6410-module: configure wm0010 interrupt trigger type

[Dmitry Torokhov]

The wm0010 driver currently defaults to IRQF_TRIGGER_FALLING when
pdata.irq_flags is unset. Unconditionally set the default trigger type
on S3C_EINT(4)'s irq_data to IRQ_TYPE_EDGE_FALLING in
wlf_gf_module_register() using irqd_set_trigger_type().

This configures the default trigger in board code in preparation for
updating wm0010 to rely on the pre-configured interrupt trigger and
dropping struct wm0010_pdata altogether.
