This patch (as856) attempts to improve the performance of uhci-hcd by
removing the asynchronous skeleton Queue Headers. They don't contain
any useful information but the controller has to read through them at
least once every millisecond, incurring a non-zero DMA overhead.
Now all the asynchronous queues are combined, along with the period-1
interrupt queue, into a single list with a single skeleton QH. The
start of the low-speed control, full-speed control, and bulk sublists
is determined by linear search. Since there should rarely be more
than a couple of QHs in the list, the searches should incur a much
smaller total load than keeping the skeleton QHs.

Commit 00c4cc6751 Oliver Endriss changed
the budget-ci driver to use interrupt mode for i2c transfers.
This also meant that a new bunch of IR bytes that were previously lost
are now received, which allowed me to better understand how the MSP430
chip works. Unfortunately it also means that the current driver gets
some assumptions wrong and might generate double keypresses for one IR
command.
The attached patch fixes this by throwing away the repeat bytes and by
associating the correct command and device bytes.

The work item function is dvb_usb_read_remote_control():
INIT_WORK(&d->rc_query_work, dvb_usb_read_remote_control, d);
and the last piece of work it does is:
schedule_delayed_work(&d->rc_query_work,msecs_to_jiffies(d->props.rc_interval));
Hence you need to call "cancel_rearming_delayed_work()" and not
"cancel_delayed_work()", correct? I certainly haven't seen this oops

Tested successfully with au6610 and gl861 devices against fi-Yllas

There is a "hack" to enable probable i2c gate in zl10535

write 0x1a to demodulator register 0x62. In my understanding this
should be fixed to demodulator code.

This patch adds driver for Sigmatek DVB-110 USB DVB-T stick. Stick has based
on hardware of Qtuantek QT1010 tuner, Zarlink ZL10353 (Intel CE 6353)
demodulator and Alcor Micro AU6610 DVB-T USB controller. HW is rather similar
as used in MSI Megasky GL861.
Currently, the driver works only in USB 2.0. In my understanding USB 1.1 is
also supported by hw but I cannot test it due to lack of USB 1.1 port. Device
supports only isochronous mode transfers. There is also eeprom in usb
controller(at least in address range 0x80 - 0xbf) for storing data, eg.
firmware. Anyway, firmware loading is not used / required by the device.
There seems to be at least one unknown I2C device in address 0xa0, probably
remote control or GPIO. Windows drivers reads registers from 0x00 to 0x07
from this unknown address.
Driver is based on gl861 module. Tuner has a lot of problems to lock with
megasky qt1010 module with this hardware with some broadcasting standards.
