Greg Kroah-Hartman 1d45e0170c spi: use container_of_cont() for to_spi_device() ...

[ Upstream commit 1007ae0d46 ]

Some places in the spi core pass in a const pointer to a device and the
default container_of() casts that away, which is not a good idea.
Preserve the proper const attribute by using container_of_const() for
to_spi_device() instead, which is what it was designed for.

Note, this removes the NULL check for a device pointer in the call, but
no one was ever checking for that return value, and a device pointer
should never be NULL overall anyway, so this should be a safe change.
