When drivers work properly, they are quiet.  Lines like this should just
be removed.

Hi,
Thanks for your patch.
This patch is now superseded by
https://lore.kernel.org/linux-staging/20250214114708.28947-10-dpenkler@gmail.com/T/#u

which uses dev_err instead of pr_err and corrects the defective 
prefix problem also.
