Hi AngeloGioacchino,

Stanley Chu has left MediaTek. 
I am the new MediaTek UFS maintainer.

Please see

https://patchwork.kernel.org/project/linux-mediatek/patch/20231117103810.527-1-chu.stanley@gmail.com/

The role of MediaTek UFS maintainer is not suitable to be handed over
to someone outside of MediaTek.

Thanks.
Peter
