The V4L2_CID_ALPHA_COMPONENT control is intended for the video capture
or memory-to-memory devices that are capable of setting up the per-pixel
alpha component to some arbitrary value. It allows to set the alpha
component for all pixels to an arbitrary value.

While tda10021 supports both DVB-C Annex A and C, it is currently
hard-coded to Annex A. Add support for Annex C and re-work the
code in order to report the delivery systems, thans to Andreas,
that passed us the register settings for the Roll-off factor.

This reverts commit ff83bd82cb.
As requested by Antti:
From a talk with him at #linuxtv irc, he strong feeling that some apps
like MythTV will do a lot a lot of I2C I/O and now it adds locks,
with utimatelly means more delays. This could cause bad effects.
There is a new patch for 3.3 that re-writes af9013 in order to limit
I2C I/O. and thus those patches could be nice to have together
because those user who has has problems are most likely MythTV users.
So, let's revert this commit for now.

Currently, for any multi-standard frontend it is assumed that it just
has a single standard capability. This is fine in some cases, but
makes things hard when there are incompatible standards in conjuction.
Eg: DVB-S can be seen as a subset of DVB-S2, but the same doesn't hold
the same for DSS. This is not specific to any driver as it is, but a
generic issue. This was handled correctly in the multiproto tree,
while such functionality is missing from the v5 API update.
http://www.linuxtv.org/pipermail/vdr/2008-November/018417.html
Later on a FE_CAN_2G_MODULATION was added as a hack to workaround this
issue in the v5 API, but that hack is incapable of addressing the
issue, as it can be used to simply distinguish between DVB-S and
DVB-S2 alone, or another X vs X2 modulation. If there are more systems,
then you have a potential issue.
An application needs to query the device capabilities before requesting
any operation from the device.

There is a potential integer overflow in uvc_ioctl_ctrl_map(). When a
large xmap->menu_count is passed from the userspace, the subsequent call
to kmalloc() will allocate a buffer smaller than expected.
map->menu_count and map->menu_info would later be used in a loop (e.g.
in uvc_query_v4l2_ctrl), which leads to out-of-bound access.
The patch checks the ioctl argument and returns -EINVAL for zero or too
large values in xmap->menu_count.

The ati_remote driver currently uses 2-byte scancodes. However, one of
those bytes is actually a checksum and therefore shouldn't be considered
as part of the scancode.
Fix the driver to only use the actual data byte as a scancode and to
check the checksum itself. Update the bundled keymaps accordingly.
Since ati_remote was only migrated to the rc subsystem for 3.2, the
previous scancodes weren't emitted on any stable kernel.
