From 5f70ea4a5c848084ab33b7a9688fc33b097dac38 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 30 Jul 2021 11:07:10 +0100 Subject: [PATCH] parport: remove non-zero check on count [ Upstream commit 0be883a0d795d9146f5325de582584147dd0dcdc ] The check for count appears to be incorrect since a non-zero count check occurs a couple of statements earlier. Currently the check is always false and the dev->port->irq != PARPORT_IRQ_NONE part of the check is never tested and the if statement is dead-code. Fix this by removing the check on count. Note that this code is pre-git history, so I can't find a sha for it.
