Subject: [PATCH v3 1/3] PCI: Convert to device_create_managed_software_node()
Date: Wed,  6 Oct 2021 14:26:41 +0300	[thread overview]
Message-ID: <20211006112643.77684-2-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20211006112643.77684-1-heikki.krogerus@linux.intel.com>

In quirk_huawei_pcie_sva(), use device_create_managed_software_node()
instead of device_add_properties() to set the "dma-can-stall"
property.

This is the last user of device_add_properties() that relied on
device_del() to take care of also calling device_remove_properties().
After this change we can finally get rid of that
device_remove_properties() call in device_del().

After that device_remove_properties() call has been removed from
device_del(), the software nodes that hold the additional device
properties become reusable and shareable as there is no longer a
default assumption that those nodes are lifetime bound the first
device they are associated with.
