Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

Querycap shouldn't set the version field (the core does that for you),
but it should set the device_caps field.

By allowing compilation on all archs, we can use static
analysis tools to test this driver.
In order to do that, replace asm/sizes.h by its generic
name (linux/sizes.h), with should keep doing the right

There are no need to store resource struct and IRQ in the driver
internal structure.
This patch remove these fields and improve error handling by using
proper return codes from devm_ioremap_resource() and devm_request_irq().

The timestamp_type field used to contain only the timestamp type. Soon it
will be used for timestamp source flags as well. Rename the field
accordingly.

The m2m-deinterlace, mem2mem_testdev and mx2_emmaprp drivers didn't set
the v4l2_dev pointer in struct video_device, even though a v4l2_device was
registered correctly. These days this v4l2_dev pointer must be set correctly,
so this patch adds that for these three drivers.

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.
devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

queue_init() is always called by v4l2_m2m_ctx_init(), which allocates
a context struct v4l2_m2m_ctx with kzalloc.
Therefore, there is no need to clear vb2_queue src/dst structs.

Using devm_kzalloc simplifies the code and ensures that the use of
devm_request_irq is safe. When kzalloc and kfree were used, the interrupt
could be triggered after the handler's data argument had been freed.
This also introduces some missing initializations of the return variable
ret, and uses devm_request_and_ioremap instead of the combination of
devm_request_mem_region and devm_ioremap.
The problem of a free after a devm_request_irq was found using the
following semantic match (http://coccinelle.lip6.fr/)
// <smpl>
@r exists@
expression e1,e2,x,a,b,c,d;
