Olli Salonen 07d45a42fa media: mn88472: reset stream ID reg if no PLP given
If the PLP given is NO_STREAM_ID_FILTER (~0u) don't try to set that into the PLP register. Set PLP to 0 instead.

Antti Palosaari 365fe4e0ce [media] mn88472: fix chip id check on probe
A register used to identify chip during probe was overwritten during
firmware download and due to that later probe's for warm chip were
failing. Detect chip from the another register, which is located on
different register bank 2.

Max Kellermann bd336e6344 [media] dvb: make DVB frontend *_ops instances "const"
These are immutable.  Making them "const" allows the compiler to move
them to the "rodata" section.

Note that cxd2841er_t_c_ops cannot be made "const", because
cxd2841er_attach() modifies it.  Ouch!
