rcar-dmac has 2 types of interrupt, 1) error IRQ (for all), 2) IRQ for each channels. If error happens on some channels, the error IRQ will be handled by 1), and "all" channels will be restarted. But in this design, error handling itself will be problem for non error channel users. This patch removes 1) handler, and handles error IRQ on 2) Signed-off-by: Magnus Damm <damm+renesas@opensource.se> [Kuninori: updated patch to adjust DMACHCR/DMAOR] Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Nguyen Viet Dung <nv-dung@jinso.co.jp> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Vinod Koul <vkoul@kernel.org>
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.
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.
