* staging: emxx_udc: Remove EMMA Mobile USB Gadget driverGeert Uytterhoeven2024-01-245-3796/+0

* staging: emxx_udc: Convert to platform remove callback returning voidUwe Kleine-König2023-04-031-4/+2
| | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

* staging: emxx_udc: Make incorrectly defined global staticKumar Kartikeya Dwivedi2021-02-072-2/+3
| | | | | | | | | | | | | | | | | The global gpio_desc pointer and int vbus_irq were defined in the header, instead put the definitions in the translation unit and make them static as there's only a single consumer, and these symbols shouldn't pollute the global namespace. This fixes the following sparse warnings for this driver: drivers/staging/emxx_udc/emxx_udc.c: note: in included file: drivers/staging/emxx_udc/emxx_udc.h:23:18: warning: symbol 'vbus_gpio' was not declared.
