In sr_mdio_read() the local variable res is used to store both little-endian and host byte order values. This prevents Sparse from helping us by flagging when endian miss matches occur - the detection process hinges on the type of variables matching the byte order of values stored in them. Address this by adding a new local variable, word, to store little-endian values; change the type of res to int, and use it to store host-byte order values. Flagged by Sparse as: .../sr9700.c:205:21: warning: incorrect type in assignment (different base types) .../sr9700.c:205:21: expected restricted __le16 [addressable] [usertype] res .../sr9700.c:205:21: got int .../sr9700.c:207:21: warning: incorrect type in assignment (different base types) .../sr9700.c:207:21: expected restricted __le16 [addressable] [usertype] res .../sr9700.c:207:21: got int .../sr9700.c:212:16: warning: incorrect type in return expression (different base types) .../sr9700.c:212:16: expected int .../sr9700.c:212:16: got restricted __le16 [addressable] [usertype] res Compile tested only.

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 reStructuredText 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.
