Jani Nikula 207ea507a1 drm/i915/dsi: fuse dsi_send_pkt_payld() and add_payld_to_queue()
Having two functions for this seems like excess duplication and
parameter juggling. Merge them together.

While at it, drop the extra error message, as wait_for_payload_credits()
already prints an error, and switch from incidental -EPERM (i.e. -1) to
actual error codes.

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.
