      [media] vp7045: fix buffer setup · fc61ccd3
      由 Florian Mickler 提交于 
      dvb_usb_device_init calls the frontend_attach method of this driver which
uses vp7045_usb_ob. In order to have a buffer ready in vp7045_usb_op, it has to
be allocated before that happens.

Luckily we can use the whole private data as the buffer as it gets separately
allocated on the heap via kzalloc in dvb_usb_device_init and is thus apt for
use via usb_control_msg.

This fixes a
	BUG: unable to handle kernel paging request at 0000000000001e78

reported by Tino Keitel and diagnosed by Dan Carpenter.

      [media] dvb-usb: improve sanity check of adap->active_fe in dvb_usb_ctrl_feed · 2d04c13a
      由 Michael Krufky 提交于 
      The check for (adap->active_fe < 0) at the top of dvb_usb_ctrl_feed is a sanity
check to ensure that adap->active_fe is valid.  Improve that sanity check
by also checking for (adap->active_fe >= adap->num_frontends_initialized)

      [media] dvb-usb: fix streaming failure on channel change · 4b5d01e9
      由 Michael Krufky 提交于 
      This fixes a bug introduced by a previous changeset entitled,
[media] dvb-usb: refactor MFE code for individual streaming config per frontend

As reported by Antti Palosaari, This error is shown by VLC when channel changed:

[0x7f1bbc000cd0] dvb access error: DMXSetFilter: failed with -1 (Invalid argument)
[0x7f1bbc000cd0] dvb access error: DMXSetFilter failed
[0x7f1bbc32f910] main stream error: cannot pre fill buffer

After my own investigations, I've determined that this error case occurs when
the application stops streaming but leaves the frontend and dvr devices open.
A typical example of this usage would be a channel change operation while
watching live television. The error occurs when the application attempts to
stream after tuning to the new channel.

To prevent this error, don't set adap->active_fe to -1 unless the application
closes the device.
