Moikka Matthias!
Idea of patch is correct, but I think implementation not. You set FE to
si2157_config on variable define, but on that point FE is NULL. FE
pointer is populated by demodulator driver, si2168. Right?
And you could split that to 3 patches too, one for prepare em28xx, one
for cxusb and last is patch itself.
regards
Antti

This is needed for PCTV 522e support.
Modify all users of si2157_config to correctly initialize all not
mentioned values to 0.
