| Subject: gpio: mockup: remove gpio debugfs when remove device |
| |
| From: Wei Yongjun <weiyongjun1@huawei.com> |
| |
| [ Upstream commit 303e6da99429510b1e4edf833afe90ac8542e747 ] |
| |
| GPIO mockup debugfs is created in gpio_mockup_probe() but |
| forgot to remove when remove device. This patch add a devm |
| managed callback for removing them. |
