# \[PATCH fix\] Revert "USB: bcma: Add a check for devm\_gpiod\_get" - From: Rafał Miłecki \ - Date: 2021-08-31 06:54:38 - List: linux-usb - Page: https://ratatoskr.run/linux-usb/2021/08/8878667 - Thread: https://ratatoskr.run/linux-usb/2021/08/8878667/t.md ```text From: Rafał Miłecki This reverts commit f3de5d857bb2362b00e2a8d4bc886cd49dcb66db. That commit broke USB on all routers that have USB always powered on and don't require toggling any GPIO. It's a majority of devices actually. The original code worked and seemed safe: vcc GPIO is optional and bcma_hci_platform_power_gpio() takes care of checking the pointer before using it.
