checkpatch: add test for assignment at start of line
Kernel style seems to prefer line wrapping an assignment with the assignment operator on the previous line like: <leading tabs> identifier = expression; over <leading tabs> identifier = expression; somewhere around a 50:1 ratio $ git grep -P "[^=]=\s*$" -- "*.[ch]" | wc -l 52008 $ git grep -P "^\s+[\*\/\+\|\%\-]?=[^=>]" | wc -l 1161 So add a --strict test for that condition.
