 error: invalid use of void expression
  1162 |  (void)!device_add_disk(vblkdev->device, vblkdev->gd, NULL);
       |        ^

Fix the build for kernels prior to v5.15 by not attempting to  access
the return value. Finally, for kernels v5.15 and newer, do not ignore
the return value and report an error if device_add_disk() fails.

78db0d7c41 tsec: Conditionally turn off clock in suspend 
Problem:
=======
In current implementation of tsec_poweroff, tsec clock is getting
turned off unconditionally.

During suspend-resume operation, there is an issue in MB1 as
explained in bug 3796711 (comment 16). Due to this, when
tsec_poweroff function is called for second suspend operation,
tsec clock is turned off even when the power state variable
"pdata->power_on" is not set to true or 1.

This causes the following warning from clock driver highlighting
that tsec clock is already disabled.

<snip>

Solution:
========

There is a check present in tsec_poweroff function to conditionally
call tsec_prepare_poweroff only if TSEC is powered on. Use the
same check to conditionally call tsec_disable_clk

a50a8e12cc devfreq: pod v2: Add support for Linux v5.19 
Currently the pod v2 governor only supports kernel upto Linux v5.17. Now
that Linux v5.19-rc2 we can enable support for this kernel by ensuring
that the definitions and functions defined in the governor_v2.h are
compatible with upstream.

8a2d6e1b54 devfreq: pod v2: build as ext module for kstable 
governor_pod_scaling_v2 will be provided as a kernel module in future
NVIDIA software deliverables for Linux platforms. As of this moment, the
function that returns the range of the device's scaling frequency hasn't
been exposed from Linux kernel for modules to call. A similar function
is implemented in the governor_pod_scaling_v2, but this function cannot
get the frequency constraints put through the PM QOS interface due to
the same reason, lack of kernel API function. An upstream kernel patch
has been proposed by the power management maintainer to provide the
function needed by governor_pod_scaling_v2, but it's not in any release
kernel yet. For now, PM QOS support is removed from
governor_pod_scaling_v2 and it will be added back when the upstream
kernel patch is available in kernel releases.

drivers_devfreq_governor_5_14.h is a copy of drivers/devfreq/governor.h
of Linux kernel 5.14. Having this copy is to avoid introducing the
dependency on Linux source for building the podgov as external module.
