Subject: [PATCH] staging: android: ion: Replace strncpy() for stracpy()
Date:   Sun,  8 Sep 2019 14:34:50 +1000

Precedence: bulk

Using strncpy() does not always terminate the destination string.
stracpy() is a alternative function that does, by using this new
function we will no longer need to insert a null separator.
