[ Upstream commit e10707d5865c90d3dfe4ef589ce02ff4287fef85 ] When adding proper support for V4L2_FIELD_ALTERNATE it was missed that this field format should trigger an interrupt for each field, not just for the whole frame. Fix this by marking it as progressive in the capture setup, which will then select the correct interrupt mode. Tested on both Gen2 and Gen3 with the result of a doubling of the frame rate for V4L2_FIELD_ALTERNATE. From a PAL video source the frame rate is now 50, which is expected for alternate field capture.

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.
