Dmitry Torokhov 78cea55c60 [media] ad5820: remove incorrect __exit markups
Even if bus is not hot-pluggable, devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

Arnd Bergmann 27430d19a9 [media] tw5864: use dev_warn instead of WARN to shut up warning
tw5864_frameinterval_get() only initializes its output when it successfully
identifies the video standard in tw5864_input. We get a warning here because
gcc can't always track the state if initialized warnings across a WARN()
macro, and thinks it might get used incorrectly in tw5864_s_parm:

media/pci/tw5864/tw5864-video.c: In function 'tw5864_s_parm':
media/pci/tw5864/tw5864-video.c:816:38: error: 'time_base.numerator' may be used uninitialized in this function [-Werror=maybe-uninitialized]
media/pci/tw5864/tw5864-video.c:819:31: error: 'time_base.denominator' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Using dev_warn() instead of WARN() avoids the __branch_check__() in
unlikely and lets the compiler see that the initialization is correct.

Philipp Zabel 89ed025d5c [media] coda: disable BWB for all codecs on CODA 960
I don't know what the BWB unit is, I guess W is for write and one of the
Bs is for burst. All I know is that there repeatedly have been issues
with it hanging on certain streams (ENGR00223231, ENGR00293425), with
various firmware versions, sometimes blocking something related to the
GDI bus or the GDI AXI adapter. There are some error cases that we don't
know how to recover from without a reboot. Apparently this unit can be
disabled by setting bit 12 in the FRAME_MEM_CTRL mailbox register to
zero, so do that to avoid crashes.

Side effects are reduced burst lengths when writing out decoded frames
to memory, so there is an "enable_bwb" module parameter to turn it back
on.

Bytesperline/stride was always overwritten by VPE to the most
adequate value based on needed alignment.

However in order to make use of arbitrary size DMA buffer it

The driver will still calculate an appropriate stride but will
use the provided one when it is larger than the calculated one.

Arnd Bergmann 3538aa6ecf [media] tc358743: fix register i2c_rd/wr functions
While testing with CONFIG_UBSAN, I got this warning:

drivers/media/i2c/tc358743.c: In function 'tc358743_probe':
drivers/media/i2c/tc358743.c:1930:1: error: the frame size of 2480 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

The problem is that the i2c_rd8/wr8/rd16/... functions in this driver pass
a pointer to a local variable into a common function, and each call to one
of them adds another variable plus redzone to the stack.

I also noticed that the way this is done is broken on big-endian machines,
as we copy the registers in CPU byte order.

To address both those problems, I'm adding two helper functions for reading
a register of up to 32 bits with correct endianess and change all other
functions to use that instead. Just to be sure we don't get the problem
back with changed optimizations in gcc, I'm also marking the new functions
as 'noinline', although my tests with gcc-7 don't require that.

We can avoid doing this by open-coding the call to i2c_transfer()
instead of calling tveeprom_read(), and not passing an i2c_client
pointer to tveeprom_hauppauge_analog(), which would ignore that
anyway.

it puts an i2c_client structure on it:

drivers/media/usb/cx231xx/cx231xx-i2c.c: In function 'cx231xx_do_i2c_scan':
drivers/media/usb/cx231xx/cx231xx-i2c.c:518:1: error: the frame size of 1248 bytes is larger than 1152 bytes [-Werror=frame-larger-than=]

This changes it to call i2c_transfer() directly instead, avoiding the
need for the structure.

Arnd Bergmann 6830733d53 [media] pvrusb2: reduce stack usage pvr2_eeprom_analyze()
The driver uses a relatively large data structure on the stack, which
showed up on my radar as we get a warning with the "latent entropy"
GCC plugin:

drivers/media/usb/pvrusb2/pvrusb2-eeprom.c:153:1: error: the frame size of 1376 bytes is larger than 1152 bytes [-Werror=frame-larger-than=]

The warning is usually hidden as we raise the warning limit to 2048
when the plugin is enabled, but I'd like to lower that again in the
future, and making this function smaller helps to do that without
build regressions.

Further analysis shows that putting an 'i2c_client' structure on
the stack is not really supported, as the embedded 'struct device'
is not initialized here, and we are only saved by the fact that
the function that is called here does not use the pointer at all.

It allows to simulate the behavior of hardware with such limitations or
to connect vivid to real hardware with such limitations.

Add the "allocators" module parameter option to let vivid use the

Songjun Wu 93d4a26c3d [media] atmel-isc: add the isc pipeline function
Image Sensor Controller has an internal image processor.
It can convert raw format to the other formats, like
RGB565, YUV420P. A module parameter 'sensor_preferred'
is used to enable or disable the pipeline function.
Some v4l2 controls are added to tuning the image when
the pipeline function is enabled.

Alexey Dobriyan 5b5e0928f7 lib/vsprintf.c: remove %Z support
Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.

Use BUILD_BUG_ON in a couple ATM drivers.

In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement.  Hopefully this patch inspires
someone else to trim vsprintf.c more.

I did not touch the "N_BYTE_ALIGMENT" macro in

I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because
it is surrounded by #if 0 ... #endif.  It is surely safe and I
confirmed "_alignment_handler" is correct.

I also fixed the "controler" I found in the same hunk in
arch/openrisc/kernel/head.S.

I also added "userspace" to the list since it is a common word in Linux.
I found some instances for "an userfaultfd", but I did not add it to the
list.  I felt it is endless to find words that start with "user" such as
"userland" etc., so must draw a line somewhere.
