This patch adds the driver for the as3645a LED flash controller. This
controller supports a high power led in flash and torch modes and an
indicator light, sometimes also called privacy light.Signed-off-by: Laurent Pinchart

When enumerating an entity, assign the entire entity specification
instead of only the first two words. (This requires giving the
specification union a name.)So far, no driver actually uses more than two words, but this will
be needed for ALSA entities.Signed-off-by: Clemens Ladisch

The field is used to select the polarity of the pixel clock signal.

The HS/VS interrupt handler needs to access the pipeline object. It
erronously tries to get it from the CCDC output video node, which isn't
necessarily included in the pipeline. This leads to a NULL pointer
dereference.Fix the bug by getting the pipeline object from the CCDC subdev entity.

Hauppauge RC-5 tables require the full scancodes. The code at budget-ci
handles it right, however, it request the rc-code to mask them with 0xff,
breaking support for some remote controllers.Fix it by not selecting a scancode mask when the driver is on full_rc5 mode.

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.Signed-off-by: Manu Abraham

The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.The semantic patch that makes this change is available

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.Signed-off-by: Haogang Chen

Instead of skipping the payload completely, which would make the
resulting image corrupted anyway, store the payload normally and mark
the buffer as erroneous. If the no_drop module parameter is set to 1 the
buffer will then be passed to userspace, and tt will then be up to the
application to decide what to do with the buffer.Signed-off-by: Laurent Pinchart
