Date: Wed, 3 Oct 2012 17:03:21 +0200 Message-Id: <1349276601-8371-27-git-send-email-florian@openwrt.org> X-Mailer: git-send-email 1.7.9.5 In-Reply-To: <1349276601-8371-1-git-send-email-florian@openwrt.org> References: <1349276601-8371-1-git-send-email-florian@openwrt.org> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 7074 Lines: 276 All users have been converted to use the OHCI platform driver instead. The driver was also doing quirky things with the internal OHCI hcd structure during suspend/resume, work that is taken care of by the core OHCI code in ohci-hub.c.
