Subject: [PATCH v2 1/2] include: linux: sysfs: Add __ATTR_NAMED macro
Date: Wed, 13 Sep 2017 14:14:07 +0530	[thread overview]
Message-ID: <2bc7a124ab925dd2c50aa8c778745d179777d50d.1505291907.git.himshijain.hj@gmail.com> (raw)
In-Reply-To: <cover.1505291907.git.himshijain.hj@gmail.com>

Add __ATTR_NAMED macro similar to __ATTR but taking name as a
string instead of implicit conversion of argument to string using
the macro _stringify(_name).
