[PATCH][next] net: hns3: remove redundant null check of an array

From: Colin King <hidden>
Date: 2021-02-03 13:11:35
Also in: kernel-janitors, lkml
Subsystem: hisilicon network subsystem 3 driver (hns3), hisilicon network subsystem driver, networking drivers, the rest · Maintainers: Jian Shen, Jijie Shao, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

From: Colin Ian King <redacted>

The null check of filp->f_path.dentry->d_iname is redundant because
it is an array of DNAME_INLINE_LEN chars and cannot be a null. Fix
this by removing the null check.

Addresses-Coverity: ("Array compared against 0")
Fixes: 04987ca1b9b6 ("net: hns3: add debugfs support for tm nodes, priority and qset info")
