[ Upstream commit518fa4e0e0] You can't memset the contents of a __user pointer. Instead, call copy_to_user to copy links.reserved (which is zeroed) to the user memory. This fixes this sparse warning: SPARSE:drivers/media/mc/mc-device.c drivers/media/mc/mc-device.c:521:16: warning: incorrect type in argument 1 (different address spaces) Fixes:f49308878d("media: media_device_enum_links32: clean a reserved field") Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Reviewed-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Signed-off-by: Sasha Levin <sashal@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.
