[PATCH] MISC: add const to bin_attribute structures
From: Bhumika Goyal
Date: Wed Aug 02 2017 - 05:10:24 EST
Add const to bin_attribute structures as they are only passed to the
functions sysfs_{remove/create}_bin_file. The arguments passed are of
type const, so declare the structures to be const.
Done using Coccinelle.
