When using modules, its common for the modules not to be loaded until quite late by userland. With the current code, driver_deferred_probe_check_state() will stop returning EPROBE_DEFER after late_initcall, which can cause module dependency resolution to fail after that. So allow a longer window of 30 seconds (picked somewhat arbitrarily, but influenced by the similar regulator core timeout value) in the case where modules are enabled.

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.
