blk_crypto_evict_key() is only called in contexts such as inode eviction where failure is not an option. So there is nothing the caller can do with errors except log them. (dm-table.c does "use" the error code, but only to pass on to upper layers, so it doesn't really count.) Just make blk_crypto_evict_key() return void and log errors itself.

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.
