Lukas Wunner b8aaa5c1f3 spi: bcm2835aux: Fix use-after-free on unbind 
commit e13ee6cc4781edaf8c7321bee19217e3702ed481 upstream.

bcm2835aux_spi_remove() accesses the driver's private data after calling
spi_unregister_master() even though that function releases the last
reference on the spi_master and thereby frees the private data.

Fix by switching over to the new devm_spi_alloc_master() helper which
keeps the private data accessible until the driver has unbound.
