Subject: b43legacy/leds: Ensure NUL-termination of LED name string
Date: Tue, 31 Jul 2018 21:14:16 +0200 [thread overview]
Message-ID: <20180731211416.36cde729@wiggum> (raw)
[-- Attachment #1: Type: text/plain, Size: 907 bytes --]
strncpy might not NUL-terminate the string, if the name equals the buffer size.
Use strlcpy instead.
