Subject: [PATCH] ASoC: Intel: sst: remove redundant variable dma_dev_name

From: Colin Ian King <colin.king@...onical.com>

The pointer dma_dev_name is assigned but never read, it is redundant
and can therefore be removed.

Cleans up clang warning:
sound/soc/intel/common/sst-firmware.c:288:3: warning: Value stored to
'dma_dev_name' is never read
