gpio: ml-ioh: Fix buffer underwrite on probe error path
[ Upstream commit 4bf4eed44bfe288f459496eaf38089502ef91a79 ]
If ioh_gpio_probe() fails on devm_irq_alloc_descs() then chip may point
to any element of chip_save array, so reverse iteration from pointer chip
may become chip_save[-1] and gpiochip_remove() will operate with wrong
memory.
The patch fix the error path of ioh_gpio_probe() to correctly bypass
chip_save array.
