From a604686c468dc0ab9492dbeaa1722cc3878b0582 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 11 Dec 2018 13:50:55 +0100 Subject: [PATCH] staging: atomisp: remove "fun" strncpy warning [for older kernels only, atomisp has been removed from upstream] gcc-8 rightfully warns that this instance of strncpy is just copying from the source, to the same source, for a few bytes. Meaning this call does nothing. As the author of the code obviously meant it to do something, but this code must be working properly, just replace the call to the kernel internal strscpy() which gcc doesn't know about, so the warning goes away. As this driver was deleted from newer kernel versions, none of this really matters but now at least we do not have to worry about a build warning in the stable trees.
