Subject: [PATCH] driver core: add CLASS_ATTR_WO()
Date: Tue, 22 Nov 2016 18:31:49 +0100 [thread overview]
Message-ID: <20161122173149.GA2841@kroah.com> (raw)
Some class subsystems are open-coding CLASS_ATTR_WO because the driver
core never provided it. Add the macro to device.h so that we can go
around and fix up the individual subsystems as needed.
