You can drop above 4 lines, they are obvious. Your "dtbs_check error"
message already defined that.

The warning message should not be wrapped, so this should be two lines.
Maybe entire warning should be in one line, at least that's what I would
do, after dropping "arch/arm64/boot/dts/".

Anyway, no need to resend just for these. Thanks for the update.
