The above commit is causing a boot regression on the Tegra210 Jetson TX1
board and reverting this commit fixes it. This also happens with
linux-6.1.y, linux-6.6.y and linux-6.7.y. I am not seeing this on the
mainline.

Test results for stable-v5.15:
     10 builds:	10 pass, 0 fail
     28 boots:	26 pass, 2 fail
     74 tests:	74 pass, 0 fail

Linux version:	5.15.148-rc1-g59db9667b9d1
Boards tested:	tegra124-jetson-tk1, tegra186-p2771-0000,
                 tegra194-p2972-0000, tegra194-p3509-0000+p3668-0000,
                 tegra20-ventana, tegra210-p2371-2180,
                 tegra210-p3450-0000, tegra30-cardhu-a04

Boot failures:	tegra210-p2371-2180

Looking at the console I am seeing the following panic ...
