mxl5xx.h doesn't carry any licensing boilerplate at all right now, so copy
the boilerplate over from the main driver file mxl5xx.c. Also, mxl5xx_defs
is missing a part of the licensing boilerplate text, so add it.
[mchehab@kernel.org: kept only the part of this patch that copied
the license from mxl5xx.c into mxl5xx.h]

In commit 3db30defab4b ("use correct MODULE_LINCESE for GPL v2 only
according to notice in header") in the upstream repository for the
mentioned four drivers at https://github.com/DigitalDevices/dddvb.git
(plus a few more which aren't part of the mainline kernel tree), the
MODULE_LICENSE was fixed to "GPL v2" and are now in sync with the
GPL copyright boilerplate. Apply this change to the kernel tree
drivers as well.

Add a V4L2 mem-to-mem scaler/CSC driver for the Pixel Pipeline (PXP)
version found on i.MX6ULL SoCs. A similar variant is used on i.MX7D.
Since this driver only uses the legacy pipeline, it should be reasonably
easy to extend it to work with the older PXP versions found on i.MX6UL,
i.MX6SX, i.MX6SL, i.MX28, and i.MX23.
The driver supports scaling and colorspace conversion. There is
currently no support for rotation, alpha-blending, and the LUTs.

The device information structure is currently copied field by field in
the uvc_device structure. As we only have two fields at the moment this
isn't much of an issue, but it prevents easy addition of new info
fields.
Fix this by storing the uvc_device_info pointer in the uvc_device
structure. As a result the uvc_device meta_format field can be removed.
The quirks field, however, needs to stay as it can be modified through a
module parameter.
As not all device have an information structure, we declare a global
"NULL" info instance that is used as a fallback when the driver_info is
empty.

pm_runtime_get_if_in_use() returns -EINVAL if runtime PM is disabled. This
should not be considered an error. Generally the driver has enabled
runtime PM already so getting this error due to runtime PM being disabled
will not happen.
Instead of checking for lesser or equal to zero, check for zero only.
Address this for drivers where this pattern exists.
This patch has been produced using the following command:
$ git grep -l pm_runtime_get_if_in_use -- drivers/media/i2c/ | \
xargs perl -i -pe 's/(pm_runtime_get_if_in_use\(.*\)) \<\= 0/!$1/'

Replace the calls to pm_runtime_get_noresume() and pm_runtime_put() with

effect with fewer calls. pm_runtime_disable() in remove is sufficient as
the device is already in RPM_SUSPENDED state.
