As described in the bug, this change causes a loss of sound on the Intel Broadwell platform (and even significantly degrades system performance when attempting to play sound).
Unfortunately, this has caused a regression. The SST and SOF drivers
cannot both be enabled for the same Intel platform in the kernel
configuration, according to Intel.
