[PATCH 3/5] gpio: aggregator: Return an error if there are no GPIOs in gpio_aggregator_parse()

From: Dan Carpenter
Date: Sat Apr 12 2025 - 06:16:09 EST


The error handling in gpio_aggregator_parse() was re-written. It now
returns success if there are no GPIOs. Restore the previous behavior
and return -EINVAL instead.

Fixes: 83c8e3df642f ("gpio: aggregator: expose aggregator created via legacy sysfs to configfs")
