holger@muscate-magnussen.de 4d84517001 V4L/DVB (5578): Workaround for bad hardare/firmware on some pluto2 devices
pluto2_driver: Workaround for pluto2 card reporting wrong number of
received packets and flooding system with interrupts.

This patch constitutes a workaround for a hardware/firmware problem of the
pluto2-based card (e.g., Satelco EasyWatch).

It can happen in rare cases that the card gets into a mode where it
always reports back a number of received packets (nbpackets) which is
larger than the maximum permissible number of packets (TS_DMA_PACKETS).
The workaround that is already in the driver in function pluto_dma_end
reports back zero received packets. In spite of the (in reality) zero
received packets the card continues to generate interrupts at a very
high rate, which can effectively stall the system.

The patch resets the TS logic, which puts the card back into normal
operations.
