Moikka!
Sounds like device is loosing warm up power during suspend. On USB there
is two callbacks to resume - resume() and reset_resume(). reset_resume()
is called when power is lost and on normal case where power has not lost
resume() is called.
I am not sure what kind of info there is available on I2C
power-management - but it is one thing to check if there is also that
same info available.
On power lost chip is reset to default - all registers and firmware also
is lost. You have to catch that somehow. If I2C power management cannot
provide that info you could use knowledge registers are set to some
default value and make decision based of that.

I have the same issue - haven't had time to look into it much.
the problem is that si2157 & si2168 doesn't resume properly from suspend.
I have attached 2 patches that disable suspend.
What i have found out:
I can resume the si2157 from suspend by replacing "goto warm" with "goto
skip_fw_download" in si2157_init()
I can 'resume' the si2168 from suspend if I set "dev->fw_loaded = 0" in
si2168_sleep()

Are you using DVB-T, T2 or C? I quickly tested T and T2 with dvbv5-
zap
and it worked (kernel media 4.5.0-rc1+).
Definitely T and T2. I had been assuming dvbv5-zap switched mode based
on the entry in the virtual channel file. In this case "BBC NEWS" is in
a T multiplex.
PCTV 282e seems to be dibcom based DVB-T only device, so you are
using
DVB-T?
Yes, 282e is T only, ditto Terratec XXS. I haven't been able to get
anything working with WinTVSoloHD or WinTVdualHD as yet.
