Subject: [PATCH AUTOSEL 4.19 01/21] i2c: rcar: optimize cacheline to minimize HW race condition
Date: Tue,  2 Mar 2021 06:58:15 -0500	[thread overview]
Message-ID: <20210302115835.63269-1-sashal@kernel.org> (raw)

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

[ Upstream commit 25c2e0fb5fefb8d7847214cf114d94c7aad8e9ce ]

'flags' and 'io' are needed first, so they should be at the beginning of
the private struct.
