The gpio-mxc driver is able to use two interrupts per gpio bank. One for the lower 16 and the other for the higher 16 gpios. The iMX27 has only one interrupt per bank. An error in the driver leads to the problem that the driver uses an invalid interrupt for the higher 16 gpios. Which in turn prevents the upper 16 gpios per bank to be used as wake source. The first patch fixes the assignment for the irq_high. The second patch adds proper return values. Which should make finding any problems in the future much easier.
