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.
