PATCH 1/4 nfc: Use standard logging styles

Using the normal logging styles is preferred over subsystem specific styles when the subsystem does not take a specific struct.

Convert nfc_<level> specific messages to pr_<level> Add newlines to uses.

If you really want it I can add it back but
if you are not aware, dynamic debug can add this by using:

echo "module nfc +fp" > <debugfs>/dynamic_debug/control echo "module nci +fp" > <debugfs>/dynamic_debug/control

If you're getting dmesg logs from customers that's a bit harder to track though.

Yes, I'm aware of that.

Exactly. I'd prefer to have the __func__ being part of the pr_fmt().

PATCH 2/4 nfc: Convert nfc_dbg to pr_debug

In reply to Joe Perches

Using the standard debugging mechanisms is better than subsystem specific ones when the subsystem doesn't use a specific struct.

Coalesce long formats.
