[PATCH 1/2] [BUG] dvb_usb_v2: return the download ret in dvb_usb_download_firmware

[Malcolm Priestley <tvboxspy@gmail.com>]

Hi antti

There some issues with dvb_usb_v2 with the lmedm04 driver.

The first being this patch, no return value from dvb_usb_download_firmware
causes system wide dead lock with COLD disconnect as system attempts to continue
to warm state.

The second is to do with d->props.bInterfaceNumber in patch 2.

In get_usb_stream_config there no handing of the struct dvb_frontend.
...
int (*get_usb_stream_config) (struct dvb_frontend *,
			struct usb_data_stream_properties *);

...
I wonder if it would be better to use adapter instead?

I also have a draft patch to use delayed work.

Regards


Malcolm
