Subject: [Outreachy kernel] [PATCH] staging: rtl8192u: ieee80211: Replaced strncpy() with strscpy()
Date: Tue, 13 Apr 2021 14:30:41 +0200 [thread overview]
Message-ID: <20210413123041.24260-1-fmdefrancesco@gmail.com> (raw)
Replaced strncpy() with strscpy() because of compilation time warnings
about possible truncation of output [-Wstringop-truncation].
Furthermore, according to the Linux official documentation, strscpy() is
preferred to strncpy.
