Subject: [PATCH] locking/lockdep: Simplify character output in seq_line()

From: Markus Elfring <elfring@...rs.sourceforge.net>

Single characters should be put into a sequence.
Thus use the corresponding function “seq_putc” for one selected call.

This issue was transformed by using the Coccinelle software.
