Ming Qian fe1c50fadc media: amphion: Drop min_queued_buffers assignment 
[ Upstream commit 5633ec763a ]

The min_queued_buffers field controls when start_streaming() is called
by the vb2 core (it delays the callback until at least N buffers are
queued). Setting it to 1 affects the timing of start_streaming(), which
breaks the seek flow in decoder scenarios and causes test failures.

The current driver implementation does not rely on this minimum buffer
requirement and handles streaming start correctly with the default
value of 0, so remove these assignments.

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 reStructuredText 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.
