of: mdio: provide devm_of_mdiobus_register()

2020-06-30T22:57:34+00:00

Implement a managed variant of of_mdiobus_register(). We need to make
mdio_devres into its own module because otherwise we'd hit circular
sumbol dependencies between phylib and of_mdio.

net: phy: don't abuse devres in devm_mdiobus_register()

2020-06-30T22:57:34+00:00

We currently have two managed helpers for mdiobus - devm_mdiobus_alloc()
and devm_mdiobus_register(). The idea behind devres is that the release
callback releases whatever resource the devm function allocates. In the
mdiobus case however there's no devres associated with the device by
devm_mdiobus_register(). Instead the release callback for
devm_mdiobus_alloc(): _devm_mdiobus_free() unregisters the device if
it is marked as managed.

This all seems wrong. The managed structure shouldn't need to know or
care about whether it's managed or not - and this is the case now for
struct mii_bus. The devres wrapper should be opaque to the managed
resource.

This changeset makes devm_mdiobus_alloc() and devm_mdiobus_register()
conform to common devres standards: devm_mdiobus_alloc() allocates a
devres structure and registers a callback that will call mdiobus_free().
__devm_mdiobus_register() allocated another devres and registers a
callback that will unregister the bus.

Documentation: devres: add missing mdio helper

2020-06-30T22:57:34+00:00

We have a devres variant of mdiobus_register() but it's not listed in
devres.rst. Add it under other mdio devm functions.

Pull staging/IIO driver updates from Greg KH:
 "Here is the large set of staging and IIO driver changes for 5.8-rc1

  Nothing major, but a lot of new IIO drivers are included in here,
  along with other core iio cleanups and changes.

  On the staging driver front, again, nothing noticable. No new
  deletions or additions, just a ton of tiny cleanups all over the tree
  done by a lot of different people. Most coding style, but many actual
  real fixes and cleanups that are nice to see.

  All of these have been in linux-next for a while with no reported
  issues"

net: devres: provide devm_register_netdev()

2020-05-23T23:56:17+00:00

Provide devm_register_netdev() - a device resource managed variant
of register_netdev(). This new helper will only work for net_device
structs that are also already managed by devres.

iio: buffer: drop devm_iio_kfifo_free() API call

2020-04-19T15:56:38+00:00

It's unused so far, so it can be removed. Also makes sense to remove it
to discourage weird uses of this call during review.
