Drop LIST_HEAD where the variable it declares is never used. tmp_list has been declared since the introduction of the driver and has never been used. The two declarations of list were introduced with the containing functions but were also not used. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier x; @@ - LIST_HEAD(x); ... when != x // </smpl> Fixes:dc78baa2b9("dmaengine: at_hdmac: new driver for the Atmel AHB DMA Controller") Fixes:4facfe7f09("dmaengine: hdmac: Split device_control") Acked-by: Ludovic Desroches <ludovic.desroches@microchip.com> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> 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.
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.
