Subject: sysfs: constify internal references to 'struct bin_attribute'
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=340d8e66c43f16a51f8fbdb1762e5b40c4e29f8e;p=thirdparty%2Fkernel%2Fstable.git

sysfs: constify internal references to 'struct bin_attribute'

The sysfs core handles 'const struct bin_attribute *'.

Adapt the internal references.
