[PATCH 1/2] ARM: SAMSUNG: Convert irq-uart to use new irq_ functions
Mark Brown

Fri Nov 26 09:51:24 EST 2010
Convert to the new irq_ versions of the IRQ operations. As well as
the textual substituion of irq_data for the raw IRQ number we also
convert the register base lookup to in s3c_irq_uart_base() to pick
the irq_data up directly.
