[Outreachy kernel] [PATCH] staging: rtl8192u: ieee80211: Replaced strncpy() with strscpy()
From: Fabio M. De Francesco
Date: Tue Apr 13 2021 - 08:31:47 EST
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.
