From c88c5035b860bc6f2e6d3c52194af1930f56b81e Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Tue, 4 Jun 2013 18:50:31 +0200 Subject: [PATCH] USB: mos7720: fix hardware flow control commit a26f009a070e840fadacb91013b2391ba7ab6cc2 upstream. The register access to enable hardware flow control depends on the device port number and not the port minor number.
