Provide __dasd_cancel_req that is called with the ccw device lock held to simplify the locking in dasd_times_out. Also this removes the following sparse warning: context imbalance in 'dasd_times_out' - different lock contexts for basic block Note: with this change dasd_schedule_device_bh is now called (via dasd_cancel_req) with the ccw device lock held. But is is already the case for other codepaths.

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.
