Subject: [PATCH v8 03/20] usb: phy: msm: Move global regulators variables to driver state
Date: Mon, 28 Apr 2014 16:34:06 +0300 [thread overview]
Message-ID: <1398692063-11372-4-git-send-email-iivanov@mm-sol.com> (raw)
In-Reply-To: <1398692063-11372-1-git-send-email-iivanov@mm-sol.com>
From: "Ivan T. Ivanov" <iivanov@mm-sol.com>
Eliminating global variables allows driver to handle multiple
device instances.
