Subject: [PATCH 2/8] net/mlxsw: use pci_zalloc_consistent instead of pci_alloc_consistent
Date: Tue, 26 Feb 2019 22:09:49 -0800	[thread overview]
Message-ID: <9ddcd9104b83c58f74cdd350f462017ad0612d4b.1551246708.git.bobbyeshleman@gmail.com> (raw)
In-Reply-To: <cover.1551246708.git.bobbyeshleman@gmail.com>

This patch replaces a call to pci_alloc_consistent and then
memset(0,) with a single call to pci_zalloc_consistent.
