>From f7cf69ae171592d133c69b9adaa5de7cfb6038ea Mon Sep 17 00:00:00 2001 From: Tejun Heo <tj@xxxxxxxxxx> Date: Wed, 31 May 2017 14:26:26 -0400 ata_parse_force_one() was incorrectly comparing @p to @endp when it should have been comparing @id. The only consequence is that it may end up using an invalid port number in "libata.force" module param instead of rejecting it.
