commitb529f1983bupstream. HMAC keys can be of any length, and atmel_sha_hmac_key_set() can only fail due to -ENOMEM. But atmel_sha_hmac_setkey() incorrectly treated any error as a "bad key length" error. Fix it to correctly propagate the -ENOMEM error code and not set any tfm result flags.

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.
