Jon Hunter 4c2880b31c irqchip/gic: Ensure gic_cpu_if_up/down() programs correct GIC instance ... Commit 3228950621 ("irqchip: gic: Preserve gic V2 bypass bits in cpu ctrl register") added a new function, gic_cpu_if_up(), to program the GIC CPU_CTRL register. This function assumes that there is only one GIC instance present and hence always uses the chip data for the primary GIC controller. Although it is not common for there to be a secondary, some devices do support a secondary. Therefore, fix this by passing gic_cpu_if_up() a pointer to the appropriate chip data structure. Similarly, the function gic_cpu_if_down() only assumes that there is a single GIC instance present. Update this function so that an instance number is passed for the appropriate GIC and return an error code on failure. The vexpress TC2 (which has a single GIC) is currently the only user of this function and so update it accordingly. Note that because the TC2 only has a single GIC, the call to gic_cpu_if_down() should always be successful.
