[PATCH] lib/vsprintf.c:Avoid extra operation in dentry_name

From: Anshul Garg
Date: Mon Feb 16 2015 - 13:50:37 EST


From: Anshul Garg <aksgarg1989@xxxxxxxxx>

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.
