This prepares to have possibly more than 3 pipes. I didn't want to continue the previous approach since the check for "are the disabled pipes the last ones" poses a combinatory explosion. We need that check because in several places of the code we have that assumption. If that ever becomes false in a new HW, other parts of the code would have to change. Now we start by considering we have info->num_pipes enabled and disable each pipe that is marked as disabled. Then it's a simple matter of checking if we have at least one pipe and that all the enabled ones are the first pipes, i.e. there are no holes in the bitmask.

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.
