When mapping the interrupts, the gpio_to_irq function did not consider the bank number of the gpio pin in question, only the offset or the interrupt number in the bank. As a result, requests for interrupts in the later banks get mapped to the first bank. This issue was discovered while enabling mmc on the new sun8i platform. The tablet I have uses a pin/interrupt from the second bank to do mmc card detection. Tested on this very device with register inspection and actual mmc card insertion/removal.

Acked-by: Maxime Ripard <redacted> Linus, could this be merged as a fix for 3.16?
