Subject: [PATCH rdma-next 2/4] gcov: Use proper duplication routine for const pointer
Date: Wed,  2 Sep 2020 11:55:11 +0300	[thread overview]
Message-ID: <20200902085513.748149-3-leon@kernel.org> (raw)
In-Reply-To: <20200902085513.748149-1-leon@kernel.org>

From: Leon Romanovsky <leonro@nvidia.com>

The filename is a const pointer, so use the proper string duplication
routine that takes into account const identifier.
