This will be useful for matching of IR tables later.
We read the eeprom anyway for dumping. Switch the dumping to
print_hex_dump_bytes and compute hash above that by
hash = 0;
for (u32 VAL) in (eeprom):
hash *= GOLDEN_RATIO_PRIME_32
hash += VAL; // while preserving endinaness
The computation is moved earlier to the flow, namely from
af9015_af9013_frontend_attach to af9015_read_config, so that
we can access the sum in af9015_read_config already.

Before each FCP transdaction, the entire 512 bytes of the FCP frame were
cleared, then values filled in.
Clear only the bytes between filled-in bytes and end of the
- request frame, or
- response frame if data from a larger response will be needed, or
- whole frame if data from a variable length response will be taken.

FCP transactions as well as CMP transactions were serialized with
mutex_lock_interruptible. It is extremely unlikly though that a signal
will arrive while a concurrent process holds the mutex. And even if one
does, the duration of a transaction is reasonably short (1.2 seconds if
all retries time out, usually much shorter).
Hence simplify the code to plain mutex_lock.

This is a portability fix and reduces stack usage.
The DMA mapping API cannot map on-stack addresses, as explained in
Documentation/DMA-mapping.txt. Convert the two cases of on-stack packet
payload buffers in firedtv (payload of write requests in avc_write and
of lock requests in cmp_lock) to slab-allocated memory.
We use the 512 bytes sized FCP frame buffer in struct firedtv for this
purpose. Previously it held only incoming FCP responses, now it holds
pending FCP requests and is then overwriten by an FCP response from the
tuner subunit. Ditto for CMP lock requests and responses. Accesses to
the payload buffer are serialized by fdtv->avc_mutex.
As a welcome side effect, stack usage of the AV/C transaction functions
is reduced by 512 bytes.
Alas, avc_register_remote_control() is a special case: It previously
did not wait for a response. To fit better in with the other FCP
transactions, let it wait for an interim response.

22-kHz tone can be driven in two ways:
1. LNBH24 can produce 22kHz continuous tone when TEN=1 ( 22 KHz tone output is
always activated ).
2. LNBH24 can reproduce 22kHz tone timings from DSQIN or EXTM pin's when TEN=0.
From LNBH24 datasheet:
"In order to improve design flexibility an external tone input pin is
available (EXTM). The EXTM is a Logic input pin which activates the 22 kHz
tone output, on the VoTX pin, by using the LNBH24 integrated tone generator
(similar to the DSQIN pin function). In fact, the output tone waveform
characteristics will always be internally controlled by the LNBH24 tone
generator and the EXTM signal will be used as a timing control for DiSEqC tone
data encoding on the VoTX output."
In NetUP Dual DVB-S2-CI card 22kHz tone timings on EXTM pin produced by
STV0900 demod:
.set_tone = stv0900_set_tone
redefine to "set_tone = lnbp21_set_tone" is not correct for "NetUP Dual
DVB-S2-CI card".
