Test results for stable-v5.10:
    15 builds:	15 pass, 0 fail
    26 boots:	26 pass, 0 fail
    64 tests:	63 pass, 1 fail

Linux version:	5.10.1-g841fca5a32cc
Boards tested:	tegra124-jetson-tk1, tegra186-p2771-0000,
                tegra194-p2972-0000, tegra20-ventana,
                tegra210-p2371-2180, tegra210-p3450-0000,
                tegra30-cardhu-a04

Test failures:	tegra194-p2972-0000: boot.py


Some changes in v5.10 exposed a minor issue in the kernel that can cause
a blank line warning to be seen. The above test is failing due to this
blank warning. Thierry has posted a fix for this [0] and should be
merged for v5.11. It was not tagged for stable, but if you OK to pull
this in once in the mainline I can send a request. Otherwise all looks
good, so ...

Thanks for testing this, and yes, I'll be glad to take this once it hits
Linus's tree, just let me know the git commit id of it there.
