I have updated f_hid.c file to latest kernel though as I knew it would be too much to ask to get support for old code.
I am just not sure about how to instantiate the function driver as earlier f_fs was instantiating the hid driver. However, after hid got converted to new function driver who is responsible for calling setup, bind and unbind functions in f_hid.c ?
Below is the glue code in android.c. drivers/usb/gadget/android.c static struct android_usb_function hid_function = { .name = "hid", .init = hid_function_init, .cleanup = hid_function_cleanup, .bind_config = hid_function_bind_config, .attributes = hid_function_attributes, };
Is there something similar in new function driver in upstream kernel? > > -- > balbi
