From: Johan Hovold Date: Mon, 26 May 2014 17:23:08 +0000 (+0200) Subject: USB: sierra: minimise no-suspend window during close X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0287d5c5cda82ebe87e79e5a298f40f0ca05e5ef;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git 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.
