You added unset, which isn't in upstream patch. This has no effect, so I'd be
for removing it. Even if it has (if it was needed), it'd be better to 1) ask
upstream to add it 2) keep it in separate patch in meanwhile (otherwise it
complicates patch rebasing during update and can be lost).

BTW (I noted that before) your patch contain trailing whitespace and mixing tab
and spaces. git am and pwclient fixes that, only when applying with patch they
get committed, so nothing serious.

$ pwclient git-am -p buildroot 991781
.git/rebase-apply/patch:59: space before tab in indent.
 	echo "  -r    list redundant entries when merging fragments"
.git/rebase-apply/patch:60: space before tab in indent.
 	echo "  -O    dir to put generated output files.  Consider setting \$KCONFIG_CONFIG instead."
.git/rebase-apply/patch:61: space before tab in indent.
 	echo "  -e    colon-separated list of br2-external trees to use (optional)"
.git/rebase-apply/patch:66: trailing whitespace.
 
.git/rebase-apply/patch:72: trailing whitespace.
