b0a3d8986a crypto: omap-sham - Use pm_runtime_irq_safe()
omap_sham_handle_queue() can be called as part of done_task tasklet.
During this its atomic and any calls to pm functions cannot sleep.

But there is a call to pm_runtime_get_sync() (which can sleep) in
omap_sham_handle_queue(), because of which the following appears:
" [  116.169969] BUG: scheduling while atomic: kworker/0:2/2676/0x00000100"

Add pm_runtime_irq_safe() to avoid this.

665503049b crypto: qat - make error and info log messages more descriptive
Convert pr_info() and pr_err() log messages to dev_info() and dev_err(),
respectively, where able.  This adds the module name and PCI B:D:F to
indicate which QAT device generated the log message.  The "QAT:" is removed
from these log messages as that is now unnecessary.  A few of these log
messages have additional spelling/contextual fixes.

Even if bus is not hot-pluggable, the devices can be bound and unbound
from the driver via sysfs, so we should not be using __init/__exit

drivers registered with platform_driver_probe() which specifically
disables sysfs bind/unbind attributes.

48eb3691e8 crypto: qat - Ensure ipad and opad are zeroed
The patch ad511e260a (crypto: qat -
Fix incorrect uses of memzero_explicit) broke hashing because the
code was in fact overwriting the qat_auth_state variable.

In fact there is no reason for the variable to exist anyway since
all we are using it for is to store ipad and opad.  So we could
simply create ipad and opad directly and avoid this whole mess.

22e4dda06d crypto: qat - fix device reset flow
When the device needs a reset, e.g. when an uncorrectable PCIe AER event
occurs, various services/data structures need to be cleaned up, the
hardware reset and the services/data structures initialized and started.
The code to perform the cleanup and initialization was not performed when
a device reset was done.

This patch moves some of the initialization code out of the .probe entry-
point into a separate function that is now called during probe as well as
after the hardware has been reset.  Similarly, a new function is added for
first cleaning up these services/data structures prior to resetting.  The
new functions are adf_dev_init() and adf_dev_shutdown(), respectively, for
which there are already prototypes but no actual functions just yet and are
now called when the device is reset and during probe/cleanup of the driver.
The down and up flows via ioctl calls has similarly been updated.

In addition, there are two other bugs in the reset flow - one in the logic
for determining whether to schedule a device reset upon receiving an
uncorrectable AER event which prevents the reset flow from being initiated,
and another with clearing the status bit indicating a device is configured
(when resetting the device the configuration remains across the reset so
the bit should not be cleared, otherwise, the necessary services will not
be re-started in adf_dev_start() after the reset - clear the bit only when
actually deleting the configuration).
