commit 810bd9066fb1871b8a9528f31f2fdbf2a8b73bf2 upstream.
The gpio-mlxbf3 driver interfaces with two GPIO controllers, device instance 0 and 1. There is a single IRQ resource shared between the two controllers, and it is found in the ACPI table for device instance 0. The driver should not use platform_get_irq(), otherwise this error is logged when probing instance 1: mlxbf3_gpio MLNXBF33:01: error -ENXIO: IRQ index 0 not found
