This is workaround / partial fix.
rtl2832u_power_ctrl() and rtl2832u_frontend_attach() needs to
be go through carefully and fix properly. There is clearly
some logical errors when handling power-management ang GPIOs...

Test: PASSED!
Working zapping on every hard/cold boot, soft/warm [re]boot and every
module(dvb_usb_rtl28xxu) [re]load.
Outside the box thinking!

That is already fixed, but I haven't sent patch yet. Currently last patch:
http://git.linuxtv.org/anttip/media_tree.git/shortlog/refs/heads/for_v3.7-10
Mabbe I will sent that fix out to mailing list right now.

Antti
