Subject: [PATCH] ASoC: imx-card: Fix mclk calculation issue for akcodec
Git-commit: f331ae5fa59fbfb748317b290648fc3f1a50d932
Patch-mainline: v5.17-rc1
References: git-fixes
Transfer the refined slots and slot_width to akcodec_get_mclk_rate()
for mclk calculation, otherwise the mclk frequency does not match
with the slots and slot_width for S16_LE format, because the default
slot_width is 32.
