Indeed FOLL_WRITE matches FAULT_FLAG_WRITE, matches GUP_FLAGS_WRITE,
and it's tempting to devise a set of Grand Unified Paging flags;
but not today.  So until then, let's rely upon the compiler to spot
the coincidence, "rather than have that subtle dependency and a
comment for it" - as you remarked in another context yesterday.

In the TRY_FMT handler the function get_scale() is called to find what the
scaler hardware will produce for a requested size.

The problem is that get_scale(struct cx231xx *dev, ..., unsigned int *vscale,
unsigned int *hscale) saves the calculated scale values into both the
pointer arguments and into dev's hscale and vscale fields.  TRY_FMT shouldn't
actually change anything in the device state.

The code to in get_scale() that writes to dev->[hv]scale can just be
deleted.  In all cases when dev's fields should be modified, get_scale()
was called with get_scale(dev, ..., &dev->hscale, &dev->vscale), so dev was
getting updated anyway.

This didn't actually cause a problem because nothing ever actually made use
of the hscale and vscale fields.  I changed cx231xx_resolution_set() to use
those fields rather than re-calculate them with a call to get_scale().

Updating [hv]scale in cx231xx_resolution_set() isn't necessary because
every call of cx231xx_resolution_set() was already preceded by a call to
get_scale() or setting the [hv]scale fields, so they will be always be
up-to-date w.r.t. width and height.

Removing the call to get_scale() from cx231xx_resolution_set() allowed
making get_scale() a static function, which is a good thing for something
with such a short name.  There is already another function with the same
name in the em28xx driver, but that one is static.

The v4l function has a better algorithm for aligning image size.

It appears that the em2800 can only scale by 50% or 100%, i.e. the only
heights supported might be 240 and 480.  In that case the old code would
set any height other than 240 to 480.  Request 240 get 240, but request 239
and then you get 480.  Change it to round to the nearest supported value.

The existing code was casting pointers to u32 and to unsigned int into
pointers to u16.  This could mess up if someone passed in an image size
greater than 65,535 and on big-endian platforms it won't work at all.

The existing bounding code would shrink an image if it was too big, but
returned ERANGE if it was too small.  The code will not shrink or expand as
necessary.

For instance the old code would change 159x243 into 156x240 to meet the

closer to what was asked for originally.

Most hardware has limits on minimum and maximum image dimensions and also
requirements about alignment.  For example, image width must be even or a
multiple of four.  Some hardware has requirements that the total image size
(width * height) be a multiple of some power of two.

v4l_bound_align_image() will enforce min and max width and height, power of
two alignment on width and height, and power of two alignment on total
image size.

It uses an efficient algorithm that will try to find the "closest" image
size that meets the requirements.

The cx25840 module's VBI initialization logic uses the current video
standard as part of its internal algorithm.  This therefore means that
we probably need to make sure that the correct video standard has been
set before initializing VBI.  (Normally we would not care about VBI,
but as described in an earlier changeset, VBI must be initialized
correctly on the cx25840 in order for the chip's hardware scaler to
operate correctly.)

It's kind of messy to force the video standard to be set before
initializing VBI (mainly because we can't know what the app really
wants that early in the initialization process).  So this patch does
the next best thing: VBI is re-initialized after any point where the
video standard has been set.

The cx25840 module requires that its VBI initialization entry point be
called in order for hardware-scaled video capture to work properly -
even if we don't care about VBI.  Making this behavior even more
subtle is that if the capture resolution is set to 720x480 - which is
the default that the pvrusb2 driver sets up - then the cx25840
bypasses the hardware scaler.  Therefore this problem does not
manifest itself until some other resolution, e.g. 640x480, is tried.
MythTV typically defaults to 640x480 or 480x480, which means that
things break whenever the driver is used with MythTV.

This all has been known for a while (since at least Nov 2006), but
recent changes in the pvrusb2 driver (specifically in regards to
sub-device support) caused this to break again.  VBI initialization
must happen *after* the chip's firmware is loaded, not before.  With
this fix, 24xxx devices work correctly again.

A related fix that is part of this changeset is that now we
re-initialize VBI any time after we issue a reset to the cx25840
driver.  Issuing a chip reset erases the state that the VBI setup
previously did.  Until the HVR-1950 came along this subtlety went
unnoticed, because the pvrusb2 driver previously never issued such a
reset.  But with the HVR-1950 we have to do that reset in order to
correctly transition from digital back to analog mode - and since the
HVR-1950 always starts in digital mode (required for the DVB side to
initialize correctly) then this device has never had a chance to work
correctly in analog mode!  Analog capture on the HVR-1950 has been
broken this *ENTIRE* time.  I had missed it until now because I've
usually been testing at the default 720x480 resolution which does not
require scaling...  What fun.  By re-initializing VBI after a cx25840
chip reset, correct behavior is restored.
