In few places relevant registers are reset to their initial value on driver load. Factor this out to new helper i801_restore_regs to avoid code duplication. Even though no actual problems are known, this patch may contribute to avoiding potential issues by: - restoring register values also in the error path of i2c_add_adapter - making restoring registers the last step (especially in i801_remove) Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Jean Delvare <jdelvare@suse.de> Acked-by: Andi Shyti <andi.shyti@kernel.org> Signed-off-by: Wolfram Sang <wsa@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.
