6eef895581A helper was recently added to the core to factorize common code between drivers, like the amount of time a driver should wait for a transfer to happen. It is of course possible to use a default value (like eg. 1s) but it is way stronger to adapt this amount of time to the transfer. Indeed, long transfers (eg. 4MiB) on a slow single-spi bus might take more than the usual second of timeout and prevent lengthy transfers. The core helper was heavily inspired by the logic applied in this driver, the only difference being the minimum amount of time which was enlarged from 0.1s to 0.5s. Use this helper instead of open-coding it.

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.
