Subject: [PATCH] scsi: dpt_i2o: remove redundant null check on array device

From: Colin Ian King <colin.king@...onical.com>

The null check on pHba->channel[chan].device is redundant because
device is an array and hence can never be null. Remove the check.

Detected by CoverityScan, CID#115362 ("Array compared against 0")
