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 adding logical operator at the end of previous
line and removing from current line, if both the lines are additions
(ie start with '+')
