usb: misc: eud: Convert to platform remove callback returning void

2023-05-28T11:38:01Z

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 ignored (apart from emitting a warning) 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. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

usb: misc: eud: Fix an error handling path in eud_probe()

2022-04-21T17:24:10Z

It is odd to call devm_add_action_or_reset() before calling the function that should be undone. Either, the "_or_reset" part should be omitted, or the action should be recorded after the resources have been allocated. Switch the order of devm_add_action_or_reset() and usb_role_switch_get().

usb: misc: eud: Add driver support for Embedded USB Debugger(EUD)

2022-02-11T11:01:02Z

Add support for control peripheral of EUD (Embedded USB Debugger) to listen to events such as USB attach/detach, pet EUD to indicate software is functional.Reusing the platform device kobj, sysfs entry 'enable' is created to enable or disable EUD. To enable the eud the following needs to be done echo 1 > /sys/bus/platform/.../enable To disable eud, following is the command echo 0 > /sys/bus/platform/.../enable Signed-off-by: Souradeep Chowdhury Link: https://lore.kernel.org/r/0ac5c2b2c8e4ce4f4f342a08b48cfc61aeaf7ee8.1644339918.git.quic_schowdhu@quicinc.com Signed-off-by: Greg Kroah-Hartman
