Bug#853894: usb-dvb device not working since kernel 4.9
Package: linux-image-4.9.0-1-amd64
Version: 4.9.2-2
After the update from kernel 4.8 to 4.9 on a testing/stretch system,
my USB DVB-T receiver stopped working.
The device is a Twinhan USB2 DVB-T tuner, so far supported by the
driver dvb_usb_vp7045.
When initializing, the driver tries to load a firmware file, and fails.
The error message is "transfer buffer not dma capable".
This issue seems similar to #852749 and #852556.
