commit 98d85f3cb912fde14593ead54dea4c1a00b3966f upstream.

When the functions replaced media entity types, the range which was
allowed for the types was incorrect. This meant that media entity types
for specific devices were not passed correctly to the userspace through
MEDIA_IOC_ENUM_ENTITIES. Fix it.

commit 6ebf75774f823ddbdbd10921006989d4df222f4a upstream.

In vpfe_s_fmt(), when the sensor format and the requested format were
the same, bpp was assigned to vpfe->bpp without being initialized first.

Grab the bpp value that is currently used by using __vpfe_get_format()
instead of its wrapper, vpfe_try_fmt().

This use of uninitialized variable has been found by compiling the
kernel with clang.

  [media] siano: make it work again with CONFIG_VMAP_STACK

Reported as a Kaffeine bug:
	https://bugs.kde.org/show_bug.cgi?id=375811

The USB control messages require DMA to work. We cannot pass
a stack-allocated buffer, as it is not warranted that the
stack would be into a DMA enabled area.

On Kernel 4.9, the default is to not accept DMA on stack anymore
on x86 architecture. On other architectures, this has been a
requirement since Kernel 2.2. So, after this patch, this driver
should likely work fine on all archs.
