From 70fbdfef4ba63eeef83b2c94eac9a5a9f913e442 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 5 Apr 2020 11:34:35 -0700 Subject: [PATCH] sysfs: remove redundant __compat_only_sysfs_link_entry_to_kobj fn Commit 9255782f7061 ("sysfs: Wrap __compat_only_sysfs_link_entry_to_kobj function to change the symlink name") made this function a wrapper around a new non-underscored function, which is a bit odd. The normal naming convention is the other way around: the underscored function is the wrappee, and the non-underscored function is the wrapper. There's only one single user (well, two call-sites in that user) of the more limited double underscore version of this function, so just remove the oddly named wrapper entirely and just add the extra NULL argument to the user. I considered just doing that in the merge, but that tends to make history really hard to read.
