From ed283e9f0a2cc0541870828c76c6c6997c51a318 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Tue, 24 Jan 2012 14:35:13 -0500 Subject: USB/PCI/PCMCIA: Clean up new_id and remove_id sysfs attribute routines This patch (as1514) cleans up some places where new_id and remove_id sysfs attributes are created and deleted. Handling both attributes in a single routine rather than a pair of routines makes the code smaller. It also prevents certain kinds of errors, like one we currently have in the USB subsystem: The removeid attribute is often created even when newid isn't (because the driver's no_dynamid_id flag is set). In the case of the PCMCIA subsystem, the newid attribute is created but never explicitly deleted. The patch adds a deletion routine.
