Linux kernel source tree

Clearing the interrupt scheme before PFR reset,
during the removal routine, could cause the hardware
errors and possibly lead to system reboot, as the PF
reset can cause the interrupt to be generated.
Place the call for PFR reset inside ice_deinit_dev(),
wait until reset and all pending transactions are done,
then call ice_clear_interrupt_scheme().
This introduces a PFR reset to multiple error paths.
Additionally, remove the call for the reset from
ice_load() - it will be a part of ice_unload() now.

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.
