Subject: [RESEND PATCH v1] checkpatch: exclude four preprocessor sub-expressions from MACRO_ARG_REUSE
Date: Wed,  7 Apr 2021 19:50:42 +0900	[thread overview]
Message-ID: <20210407105042.25380-1-mailhol.vincent@wanadoo.fr> (raw)

__must_be_array, offsetof, sizeof_field and __stringify are all
preprocessor macros and do not evaluate their arguments. As such, it
is safe not to warn when arguments are being reused in those four
sub-expressions.

Exclude those so that they can pass checkpatch.
