Subject: [igt-dev] [PATCH v18 3/6] lib: igt_gt: add eb flags to class helper
Date: Mon,  8 Apr 2019 01:37:51 +0300	[thread overview]
Message-ID: <20190407223754.6940-4-andi@etezian.org> (raw)
In-Reply-To: <20190407223754.6940-1-andi@etezian.org>

From: Andi Shyti <andi.shyti@intel.com>

we have a "class/instance to eb flags" helper but not the
opposite, add it.
