Subject: [PATCH AUTOSEL 4.9 24/73] tua6100: Avoid build warnings.
Date: Mon, 15 Jul 2019 10:35:40 -0400 [thread overview]
Message-ID: <20190715143629.10893-24-sashal@kernel.org> (raw)
In-Reply-To: <20190715143629.10893-1-sashal@kernel.org>
From: "David S. Miller" <davem@davemloft.net>
[ Upstream commit 621ccc6cc5f8d6730b740d31d4818227866c93c9 ]
Rename _P to _P_VAL and _R to _R_VAL to avoid global
namespace conflicts:
