From 0287d5c5cda82ebe87e79e5a298f40f0ca05e5ef Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 26 May 2014 19:23:08 +0200 Subject: [PATCH] USB: sierra: minimise no-suspend window during close Move usb_autopm_get_interface_no_resume to the end of close(). This makes the window during which suspend is prevented before the final put in USB serial core slightly smaller.
