Hi,
The DVB-T initial tuning information for Crystal Palace in the UK is completely
obsolete - despite my two attempts to submit an updated version over the YEARS.
Where is the best place to send this information, please?

Hello,
The following patch series is my first stab at abstracting vma handling
from the various media drivers. After this patch set drivers have to know
much less details about vmas, their types, and locking. My motivation for
the series is that I want to change get_user_pages() locking and I
Conversion to the use of pinned pfns made some functions unused. Remove
them. Also there's no need to lock mmap_sem in __buf_prepare() anymore.

Convert g2d_userptr_get_dma_addr() to pin pages using get_vaddr_pfn().
This removes the knowledge about vmas and mmap_sem locking from exynos

Teach vb2_queue_or_prepare_buf() to get pfns underlying these buffers

Hi!
After giving up on my PCTV 340e usb stick, got myself a blackgold
bgt3620, as, supposedly, had a fully functional linux support.
Unfortunately, I'm using kernel 3.12 (and 3.13). This means that the
driver supplied by manufacturer doesn't compile as it does in kubuntu

The edid array is copied to kernelspace by the v4l2 core, so drivers
shouldn't see the __user annotation. This conforms to other structs like
v4l2_ext_controls where the data pointed to is copied to from user to
kernelspace.

The notify function is a void function, yet the v4l2_subdev_notify
define uses it in a ? : construction, which causes sparse warnings.
Replace the define by a static inline function and move it to
v4l2-device.h, which is where it belongs since it needs to know the

Fix the use of __user in the check_array_args() prototype: instead of
using 'void * __user *' you should use 'void __user **' for sparse to

assignment.
