Subject: Bluetooth: 6lowpan: Make variable header_ops constant
X-Git-Tag: v5.4-rc1~131^2~48^2~14
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=569428dabc3e2523ca2b357e7d86412df1dd1e6a;p=linux.git

Bluetooth: 6lowpan: Make variable header_ops constant

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.
