Compiled and booted on my test system. No dmesg regressions.

Tested-by: Shuah Khan <skhan@linuxfoundation.org>

Upgrading to Ubuntu 21.10 caused issues with the boot related to
zstd compression which is the default initramfs.conf for 21.10

If others run into this:

Change the default to lz4. I ended up enabling
CONFIG_DECOMPRESS_ZSTD=y for 5.4 since it has support for ZSTD

On another note CONFIG_ZSTD_DECOMPRESS and CONFIG_DECOMPRESS_ZSTD
naming rather confusing.

thanks,
