#1691669 — [PATCH] xen: xen-pciback: remove DRIVER_ATTR() usage

FromGreg KH <gregkh@linuxfoundation.org>
Date2017-07-19 15:00 +0200
Subject[PATCH] xen: xen-pciback: remove DRIVER_ATTR() usage
Message-ID<u4WK7-fH-53@gated-at.bofh.it>
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

It's better to be explicit and use the DRIVER_ATTR_RW() and
DRIVER_ATTR_RO() macros when defining a driver's sysfs file.

Bonus is this fixes up a checkpatch.pl warning.

This is part of a series to drop DRIVER_ATTR() from the tree entirely.

Shouldn't this be named quirks_store()?

that, sorry.

Let me go make a v2...

I'll take this through the Xen tree, unless you want to use your tree.
