[PATCH u-boot 1/4] checkpatch: Fix unescaped brace warning

[Andrew Jeffery]

Running checkpatch using Ubuntu 18.04's packaged perl
(5.26.1-6ubuntu0.1) gave the following output:

    Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/^(\+.*(?:do|\))){ <-- HERE / at ./scripts/checkpatch.pl line 3267

Escape the brace to avoid the warning.
