Subject: [PATCH 16/16] phy: phy-core: fix initcall level
Date: Wed, 26 Aug 2015 14:28:28 +0200 [thread overview]
Message-ID: <1440592108-3740-17-git-send-email-holler@ahsoftware.de> (raw)
In-Reply-To: <1440592108-3740-1-git-send-email-holler@ahsoftware.de>
The phy-core has to be initialized before other dependent usb-drivers,
otherwise a crash might occur.
Currently phy_core_init() is called in the initcall-level device, which is
the same level where most usb-drivers will end up. By luck this seemed to
have been called most of the time before other usb-drivers without having
been explicitly enforced. But if phy_core_init() is not called before a
dependent driver, a null-pointer exception might occur (e.g. because the
phy device class isn't registered).
To fix this, phy_core_init() is moved to the initcall-level fs (right
before the standard initcall level device).
