Kieran Bingham fcd054c733 media: vsp1: Fix BRx conditional path in WPF commit `639fa43d59` upstream. When a BRx is provided by a pipeline, the WPF must determine the master layer. Currently the condition to check this identifies pipe->bru \|\| pipe->num_inputs > 1. The code then moves on to dereference pipe->bru, thus the check fails static analysers on the possibility that pipe->num_inputs could be greater than 1 without pipe->bru being set. The reality is that the pipeline must have a BRx to support more than one input, thus this could never cause a fault - however it also identifies that the num_inputs > 1 check is redundant. Remove the redundant check - and always configure the master layer appropriately when we have a BRx configured in our pipeline.

README

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
