Subject: [PATCH] mac80211: remove unnecessary NULL check in ieee80211_register_hw()
Date: Mon, 28 Jun 2021 13:10:38 +0300	[thread overview]
Message-ID: <YNmgHi7Rh3SISdog@mwanda> (raw)

The address "&sband->iftype_data[i]" points to an array at the end of
struct.  It can't be NULL and so the check can be removed.

Fixes: bac2fd3d7534 ("mac80211: remove use of ieee80211_get_he_sta_cap()")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>

This patch doesn't really *fix* anything of course.  I just added the
Fixes tag to help reviewers.
