From 8edb79af88efc6e49e735f9baf61d9f0748b881f Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Wed, 7 Apr 2021 11:49:27 +0800 Subject: [PATCH] iio: light: gp2ap002: Fix rumtime PM imbalance on error When devm_request_threaded_irq() fails, we should decrease the runtime PM counter to keep the counter balanced. But when iio_device_register() fails, we need not to decrease it because we have already decreased it before.
