I used pr_err in the SF2 driver to be consistent with the rest of the code which only uses pr_err and pr_info.
I was thinking about adding ds_err and ds_port_err to print errors for ds->master_dev and ds->ports[port], but that might be overkill. What do you think? Or local to the driver for the moment, like mvsw_err maybe?
I tend to use warn for cases where the user cannot really do something about the situation, but an hardware problem is indeed critical, so I agree with you to use error over warn here.
Thanks, Vivien
