From 9255782f70614c89b1a15ec6997c4b72ce9e630a Mon Sep 17 00:00:00 2001 From: Sourabh Jain Date: Wed, 11 Dec 2019 21:39:06 +0530 Subject: sysfs: Wrap __compat_only_sysfs_link_entry_to_kobj function to change the symlink name The __compat_only_sysfs_link_entry_to_kobj function creates a symlink to a kobject but doesn't provide an option to change the symlink file name. This patch adds a wrapper function compat_only_sysfs_link_entry_to_kobj that extends the __compat_only_sysfs_link_entry_to_kobj functionality which allows function caller to customize the symlink name.
