Subject: [PATCH 7/7] drivers/net/can/cc770/cc770_platform.c: adjust suspicious bit operation

From: Julia Lawall <Julia.Lawall@...6.fr>

CPUIF_DSC is 0x40, so it would seem that & is wanted rather than |.

This problem was found using Coccinelle (http://coccinelle.lip6.fr/).

Signed-off-by: Julia Lawall <julia@...u.dk>
