MSI digivox mini II works even with remote=2 module parameter. Check
for manufacturer and if it is Afatech, use af9015_ir_table_msi and
af9015_rc_keys_msi.
The device itself is 15a4:9016.

NACK
Device ID 15a4:9016 is reference design ID and it is used by vary many
devices. Also manufacturer string "Afatech" is chipset default one. This
leads MSI remote in question configured for many devices using default /
reference values which I don't like good idea. Strings and other USB
settings are stored to the device eeprom.
Empia (em28xx) driver uses eeprom hashing for identifying reference ID
devices. This approach is better because it uses all eeprom bytes. I
hope you could implement similar eeprom hashing to af9015.

So as a final patch, add support for hash and one hash entry
for MSI digi vox mini II:
iManufacturer 1 Afatech
iProduct 2 DVB-T 2
iSerial 3 010101010600001
It is now handled with proper IR and key map tables.

1.6.5.7
Add af9015_setup structure to hold (right now only remote) setup
of distinct receivers.
Add af9015_setup_match for matching ids against tables.
This is for easier matching different kind of ids against tables
to obtain setups. Currently module parameters and usb vendor ids
are switched into and matched against tables. Hashes will follow.

What do you think about the following patches?

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.

Does this sum contain all 256 bytes from EEPROM? 256/4 is 64.

Yes it does. It is computed as a hashed sum of 32-bit numbers (4 bytes)
-- speed (does not matter) and larger space of hashes. Hence the
division by 4. The cast does the trick: ((u32 *)eeprom)[reg] -- reg
index is on a 4-byte basis.

OK, true. Anyhow, I don't know if this hashing formula is good enough -
changing it later could be really pain. I compared it to the one used
for em28xx driver and it was different. Could someone with better
knowledge check that?
Generally it is good and ready for submission.
