Daniel Schaefer 0063a2822d media: uvcvideo: Override default flags 
[ Upstream commit 86419686e66da5b90a07fb8a40ab138fe97189b5 ]

When the UVC device has a control that is readonly it doesn't set the
SET_CUR flag. For example the privacy control has SET_CUR flag set in
the defaults in the `uvc_ctrls` variable. Even if the device does not
have it set, it's not cleared by uvc_ctrl_get_flags().

Originally written with assignment in commit 859086ae36 ("media:
uvcvideo: Apply flags from device to actual properties"). But changed to
|= in commit 0dc68cabdb ("media: uvcvideo: Prevent setting unavailable
flags"). It would not clear the default flags.

With this patch applied the correct flags are reported to user space.
Tested with:

```
> v4l2-ctl --list-ctrls | grep privacy
privacy 0x009a0910 (bool)   : default=0 value=0 flags=read-only
```

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
