Subject: [PATCH 4.19 80/99] ASoC: stm32: fix sai driver name initialisation

From: Arnaud Pouliquen <arnaud.pouliquen@...com>

commit 17d3069ccf06970e2db3f7cbf4335f207524279e upstream.

This patch fixes the sai driver structure overwriting which results in
a cpu dai name equal NULL.

Fixes: 3e086ed ("ASoC: stm32: add SAI driver")
