checkpatch: add fix option for LOGICAL_CONTINUATIONS
Currently, checkpatch warns if logical continuations are placed at the
start of a line and not at the end of previous line.
E.g., running checkpatch on commit 3485507fc272 ("staging: bcm2835-camera:
Reduce length of enum names") reports:
CHECK:LOGICAL_CONTINUATIONS: Logical continuations should be on the previous line
+ if (!ret
+ && camera_port ==
Provide a simple fix by inserting logical operator at the last
non-comment, non-whitespace char of the previous line and removing from
current line, if both the lines are additions(ie start with '+')
