Calling it earlier won't work, as we need to load the firmware before
sending the power control commands on some devices.
Probably the best here is to pass an extra optional function parameter
that will initialize the mutex before calling any functions.
Btw, if it broke here, the DMA fixes will likely break on other drivers.
So, after Jörg tests this patch, I'll work on a patch series addressing
this issue on the other drivers I touched.

[PATCH RFC] cinergyT2-core: initialize the mutex early
NOTE: don't merge this patch as-is... I actually folded two patches
together here, in order to make easier to test, but the best is to
place the changes at the core first, and then the changes at the
drivers that would need an early init.
The mutex used to protect the URB data buffer needs to be
inialized early, as otherwise it will cause an OOPS:

Subject: [PATCH] [media] dvb-usb: allow early initialization of usb device
priv data
On some drivers, we need to initialize a mutex before calling
power control or firmware download routines. Add an extra
parameter to allow it.
