commit0d6434e10bupstream. The only motivation for using -EAGAIN in commit0542ad88fb("firmware loader: Fix _request_firmware_load() return val for fw load abort") was to distinguish the error from -ENOMEM, and so there is no real reason in keeping it. -EAGAIN is typically used to tell the userspace to try something again and in this case re-using the sysfs loading interface cannot be retried when a timeout happens, so the return value is also bogus. -ETIMEDOUT is received when the wait times out and returning that is much more telling of what the reason for the failure was. So, just propagate that instead of returning -EAGAIN.

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.
