checkpatch: add fix option for ASSIGNMENT_CONTINUATIONS
Currently, checkpatch warns us if an assignment operator is placed at the start of a line and not at the end of previous line. E.g., running checkpatch on commit 8195b1396ec8 ("hv_netvsc: fix deadlock on hotplug") reports: CHECK: Assignment operator '=' should be on the previous line + struct netvsc_device *nvdev + = container_of(w, struct netvsc_device, subchan_work); Provide a simple fix by appending assignment operator to the previous line and removing from the current line, if both the lines are additions (ie start with '+') Link: https://lkml.kernel.org/r/20201121120407.22942-1-yashsri421@gmail.com Signed-off-by: Aditya Srivastava <yashsri421@gmail.com> Acked-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
