[PATCH] ASoC: SOF: mediatek: mt8195: remove a redundant comparison of sram

From: YC Hung
Date: Thu Dec 15 2022 - 01:11:16 EST


DSP SRAM is not used for audio shared buffer between host and DSP so
TOTAL_SIZE_SHARED_SRAM_FROM_TAIL is zero. Remove the definition and
redundant comparison to fix coverity "unsigned compared against 0".
