Subject: ARM: SAMSUNG: Convert irq-uart to use new irq_ functions
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=27b31e56239b44608cad176c36c384c0265f8da5;p=linux-beck.git

ARM: SAMSUNG: Convert irq-uart to use new irq_ functions

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.
