checkpatch: extend author Signed-off-by check for split From: header
Checkpatch did not handle cases where the author From: header was split
into multiple lines. The author identity could not be resolved and
checkpatch generated a false NO_AUTHOR_SIGN_OFF warning.
A typical example is commit e33bcbab16d1 ("tee: add support for session's
client UUID generation"). When checkpatch was run on this commit, it
displayed:
"WARNING:NO_AUTHOR_SIGN_OFF: Missing Signed-off-by: line by nominal
patch author ''"
This was due to split header lines not being handled properly and the
author himself wrote in commit cd2614967d8b ("checkpatch: warn if missing
author Signed-off-by"):
"Split From: headers are not fully handled: only the first part
is compared."
Support split From: headers by correctly parsing the header extension
lines. RFC 5322, Section-2.2.3 stated that each extended line must start
with a WSP character (a space or htab). The solution was therefore to
concatenate the lines which start with a WSP to get the correct long
header.
