SDCA Bug Fixes

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:

Some small SDCA bug fixes reported from various sources. An array bounds
check, an uninitialised variable and some memory allocations that should
zero initialise.

Charles Keepax (3):
  ASoC: SDCA: Fix off by one error in IRQ bound check
  ASoC: SDCA: Avoid use of uninitialised local name variable
  ASoC: SDCA: Update memory allocations to zero initialise
