[ Upstream commit2bc55eaeb8] The common I/O layer delays the ADD uevent for subchannels and delegates generating this uevent to the individual subchannel drivers. The vfio-ccw I/O subchannel driver, however, did not do that, and will not generate an ADD uevent for subchannels that had not been bound to a different driver (or none at all, which also triggers the uevent). Generate the ADD uevent at the end of the probe function if uevents were still suppressed for the device.

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.
