[V3,00/17] Add Scarlett Gen 3 support

Message

Geoffrey D. Bennett June 22, 2021, 5 p.m. UTC

This patch series adds a fixed version of Scarlett Gen 3 support on
top of the previous "Refactor Scarlett Gen 2 support" patches 1-15/31.

Two differences from the previous patches 16-31/31:

- Add patch from Takashi fixing scarlett2_add_new_ctl()

- Don't increase MAX_ID_ELEMS

I tested the above changes on the 18i20 Gen 3 and confirmed no crash
with 439 controls and MAX_ID_ELEMS 256.
