usb_control_msg initiates (and waits for completion of) a dma transfer using
the supplied buffer. That buffer thus has to be seperately allocated on
the heap.
In lib/dma_debug.c the function check_for_stack even warns about it:

The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.
Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.
options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.
With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.

This patch adds calls to i2c_gate_ctrl in the qt1010 dvb tuner module,
while removing the temporary hack in au6610 and gl861.
Tested successfully against fi-Oulu frequencies with
MSI Megasky 580 GL861 and Sigmatek DVB-110 AU6610.

gl861: (MSI Megasky)
- hack for enable ZL10353 / QT1010 I2C gate
- use new QT1010 module instead of old code
au6610: (Sigmatek DVB-110)
- hack for enable ZL10353 / QT1010 I2C gate
- use new QT1010 module instead of old code
Tested successfully with au6610 and gl861 devices against fi-Yllas
frequencies. Now it locks perfectly with both devices.
There is a "hack" to enable probable i2c gate in zl10535
demodulator. QT1010 doesn't respond to any i2c messages before we
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.
