Once upon a time the radio-miropcm20 driver had RDS support. However, after
some internal kernel changes that support was removed. Now that we have a
nice RDS API I have been working on adding back this support. It has been

Commit 0ba2aeb6da increased the internal control ranges
to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value
control values in a division or modulus operations since not all architectures support
those natively.
Luckily, in almost all cases it is possible to just cast to 32 bits (the control value
is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to
use do_div in one function.

Rather than having two unions for all types just keep 'val' and
'cur.val' and use the p_cur and p_new unions to access all others.
The only reason for keeping 'val' and 'cur.val' is that it is used
all over, so converting this as well would be a huge job.

It seems that, on such arch, the includes from asm/ should be

The proper fix would be to patch the arch files, but, as
this fix is trivial, apply it. Also, we generally put the

"A series of patches that fix compilation on non-x86 archs.
While most of them are just build fixes, there are some fixes for real
bugs, as there are a number of drivers using dynamic stack allocation.
A few of those might be considered a security risk, if the i2c-dev
module is loaded, as someone could be sending very long I2C data that
could potentially overflow the Kernel stack. Ok, as using /dev/i2c-*
devnodes usually requires root on usual distros, and exploiting it
would require a DVB board or USB stick, the risk is not high"

"This series include:

- a new frontend (cx24117)
- a new I2C camera flash driver (lm3560)
- a new mem2mem driver for TI SoC (ti-vpe)
- support for Raphael r828d added to r820t driver
- some improvements on buffer allocation at VB2 core
- usual driver fixes and improvements
PS this time, we have a smaller number of patches. While it is hard
to pinpoint to the reasons, I believe that it is mainly due to:
1) there are several patch series ready, but depending on DT review.
I decided to grant some extra time for DT maintainers to look on
it, as they're expecting to have more time with the changes agreed
during ARM mini-summit and KS. If they can't review in time for
3.14, I'll review myself and apply for the next merge window.
2) I suspect that having both LinuxCon EU and LinuxCon NA happening
during the same merge window affected the development
productivity, as several core media developers participated on
both events"
