I think it should be dev_err() too. The driver has inconsistently used
warn and err log levels in similar functions as well. But I was planning
to tackle those in a standalone patch after the printk's are gone. Or do
you think it should be part of this patchset?

Got it. Thanks for the patch suggestion. Although yes, since I still have project
starter tasks pending for my outreachy application(will have to prioritize
them) I'm not sure if I will be able to get this done right away. Will try to
though.

Thanks for the ack. Since I'll have to revise and resend this patch as v2,
should I not add your ack tag as the patch will be reviewed again? Just
wondering what the etiquette is.
Though normally are patches supposed to be resent as new versions when adding
ack tags?
