Commit b0a3d8986a ("crypto: omap-sham - Use pm_runtime_irq_safe()") added
the use of pm_runtime_irq_safe() as pm_runtime_get_sync() was called
from a tasklet.
We now use the crypto engine queue instead of a custom queue since
commit 33c3d434d91 ("crypto: omap-sham - convert to use crypto engine").
We want to drop the use of pm_runtime_irq_safe() in general as it takes a
permanent usage count on the parent device causing issues for power
management.
Based on testing with CONFIG_DEBUG_ATOMIC_SLEEP=y, modprobe omap-sham,
followed by modprobe tcrypt sec=1 mode=423, I have not been able to
reproduce the scheduling while atomic issue seen earlier with current
kernels and we can just drop the call to pm_runtime_irq_safe().

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.
