From 9b41b92bbae6a4d3e1f3adde87864fd481037814 Mon Sep 17 00:00:00 2001 From: Allen Hung Date: Fri, 15 Jul 2016 17:42:22 +0800 Subject: [PATCH] dmi-id: don't free dev structure after calling device_register dmi_dev is freed in error exit code but, according to the document of device_register, it should never directly free device structure after calling this function, even if it returned an error! Use put_device() instead.
