There are a couple of duplicate logs which makes harder than needed to
follow the error flows. Add __func__ or make the log unique.

This one seems bit unrelated to the change and makes error message inconsistent with:
https://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire.git/tree/drivers/soundwire/stream.c?h=next&id=545c365185a47672b1d5cc13c84057a1e874993c#n1498

which actually brings me to another suggestion, can this error message perhaps be just moved into do_bank_switch() function itself, instead of being duplicated multiple times or alternatively just also prefix all of them with function name?
