There are a number of other boards that need such fixing too. And the
commit in question does not do a good job of explaining why it was
needed in the first place. The description just repeats what can be
inferred by reading the patch.

gpio: davinci: Do not assume continuous IRQ numbering

Currently the driver assumes that the interrupts are continuous
and does platform_get_irq only once and assumes the rest are continuous,
instead call platform_get_irq for all the interrupts and store them
in an array for later use.

Can we revert the offending commit instead?
