The si2157 driver was recently broken so that trying to tune to channels
with a bandwidth of less than 7MHz always resulted in an error. Getting
the bandwidth after digital tuning has always returned erroneous values.
Furthermore, tune requests for DVB-C Annex C were rejected with -EINVAL,
although it should work with the same settings as for DVB-C Annex A.
The following three patches address all these issues.
With all three patches applied, the driver has been verified with a
Si2157-A30 to successfully:
- accept tune requests for DVB-C Annex A/B/C, DVB-T/T2 and ISDB-T
- receive actual 8MHz DVB-C Annex A, DVB-T and DVB-T2 signals
I do not have any DVB-C Annex B/C nor ISDB-T signals available.
