Subject: [PATCH 0/2] powerpc: gpio_mdio: Simplify gpio_mdio_probe()

While wondering if it was correct to call mdiobus_free() in the remove
function and only kfree() in the error handling of the probe, I
arrived at the conclusion that the code could be simpler here.

Patch 1 uses mdiobus_alloc_size() instead of a hand written
mdiobus_alloc() + kzalloc(). it also uses the devm_ version in order to
save some LoC (and answer my initial question)

Patch 2 uses devm_of_mdiobus_register() to completly remove the .remove()
function and save some more LoC.

Both patches are compile tested only.

Christophe JAILLET (2):
  powerpc: gpio_mdio: Use devm_mdiobus_alloc_size()
  powerpc: gpio_mdio: Use devm_of_mdiobus_register()
