Subject: checkpatch: Fix false DT_SPLIT_BINDING_PATCH warnings
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a45ff9dd3fec5d604f99b2665c40db26ce81ec0c;p=thirdparty%2Fkernel%2Flinux.git

checkpatch: Fix false DT_SPLIT_BINDING_PATCH warnings

Patches which both remove and add/modify DT binding files are
incorrectly flagged as needing to split the patch. The issue is the
check sees "dev/null" as one of the files in the patch which is not a DT
binding file. Add "dev/null" to the skipped files.
