Subject[PATCH] lib/vsprintf.c:Avoid extra operation in dentry_name
Date
From: Anshul Garg <aksgarg1989@gmail.com>

Remove unnecessary increment and decrement operation
in dentry_name function as after increment operation
loop is breaked and then decrement operation is
performed. So remove increment and decrement operation
from the function.
