Subject: [PATCH] i2c: m65xx: drop superfluous quirk structure
Date: Mon, 27 Feb 2017 20:25:05 +0100	[thread overview]
Message-ID: <20170227192505.6449-1-wsa@the-dreams.de> (raw)

All length fields in Linux I2C are u16, so a HW length limitation of 16
bit lengths is not a limitation. Remove the quirk structure.

Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

Compile tested only, don't have the hardware. Would appreciate if one of you
had the time to test this. Thank you!
