Subject: MIPS: RB532: remove useless CF GPIO initialisation
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=84c2c562c101bd84ea0f796b9838296da1bf859e;p=linux-2.6-omap-h63xx.git

MIPS: RB532: remove useless CF GPIO initialisation

As the pata-rb532-cf driver calls gpio_direction_input(), the calls to
rb532_gpio_set_func() and rb532_gpio_direction_input() are not needed since
the alternate function is automatically being disabled when changing the
GPIO pin direction.
The later two calls to rb532_gpio_set_{ilevel,istat}() are implicitly being
done by the IRQ initialisation of pata-rb532-cf.
