Subject: [PATCH] Bluetooth: 6lowpan: Make variable header_ops constant
Date: Thu, 15 Aug 2019 11:22:55 +0530
Message-ID: <> (raw)

Static variable header_ops, of type header_ops, is used only once, when
it is assigned to field header_ops of a variable having type net_device.
This corresponding field is declared as const in the definition of
net_device. Hence make header_ops constant as well to protect it from
unnecessary modification.
Issue found with Coccinelle.
