This was harmless while the drivers\nwere built-in, but once they can be built as modules and unbound/rmmod'd,\ndevm frees the gpio_chip's memory while it is still registered, causing a\nuse-after-free.\n\nRegister it with devm_gpiochip_add_data() so it shares the same\ndevice-managed lifecycle, which also lets the manual gpiochip_remove()\nerror paths go away."
