Subject: scsi: dpt_i2o: remove redundant null check on array device
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0b7250f93f02a8aaa80146c34c08e4596f0a1e1d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

scsi: dpt_i2o: remove redundant null check on array device

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")
