+Subject: [PATCH 059/203] pinctrl-bcm2835: Only request the interrupts listed
+ in the DTB
+
+Although the GPIO controller can generate three interrupts (four counting
+the common one), the device tree files currently only specify two. In the
+absence of the third, simply don't register that interrupt (as opposed to
+registering 0), which has the effect of making it impossible to generate
+interrupts for GPIOs 46-53 which, since they share pins with the SD card
+interface, is unlikely to be a problem.
