rc: raw decoder for keymap protocol is not loaded on register

2017-03-18T11:14:34+00:00

commit 413808685dd7c9b54bbc5af79da2eaddd0fc3cb2 upstream.

When the protocol is set via the sysfs protocols attribute, the
decoder is loaded. However, when it is not when a device is first
plugged in or registered.

dw2102: don't do DMA on stack

2017-03-18T11:14:30+00:00

commit 606142af57dad981b78707234cfbd15f9f7b7125 upstream.

On Kernel 4.9, WARNINGs about doing DMA on stack are hit at
the dw2102 driver: one in su3000_power_ctrl() and the other in tt_s2_4600_frontend_attach().

Both were due to the use of buffers on the stack as parameters to
dvb_usb_generic_rw() and the resulting attempt to do DMA with them.

The device was non-functional as a result.

So, switch this driver over to use a buffer within the device state
structure, as has been done with other DVB-USB drivers.

Tested with TechnoTrend TT-connect S2-4600.

media: Properly pass through media entity types in entity enumeration

2017-03-12T05:41:41+00:00

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.

cxd2820r: fix gpio null pointer dereference

commit 0ffb94b6cc5df6376ab6bff5b80075641f6716f8 upstream.

Setting GPIOs during probe causes null pointer deference when
GPIOLIB was not selected by Kconfig. Initialize driver private
field before calling set gpios.

It is regressing bug since 4.9.

am437x-vpfe: always assign bpp variable

2017-03-12T05:41:40+00:00

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.

siano: make it work again with CONFIG_VMAP_STACK

2017-02-23T16:44:35+00:00

commit f9c85ee67164b37f9296eab3b754e543e4e96a1c upstream.

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.
