Subject: [PATCH 04/27] powerpc/fsl_pci: Don't change ppc_swiotlb_enable after swiotlb_subsys_init
Date: Wed, 25 Mar 2015 16:35:38 +1100	[thread overview]
Message-ID: <1427261761-22952-5-git-send-email-dja@axtens.net> (raw)
In-Reply-To: <1427261761-22952-1-git-send-email-dja@axtens.net>

The only function that checks ppc_swiotlb_enable is swiotlb_subsys_init.
The code in fsl_pci.c is called well after that, so don't bother
changing it.

(ppc_swiotlb is usually set in swiotlb_detect_4g, which is called by
a number of arch initcalls.)
