Subject: [PATCH v1 5/8] software node: Imply kobj_to_swnode() to be no-op
Date: Sun, 28 Mar 2021 00:20:09 +0200	[thread overview]
Message-ID: <20210327222012.54103-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210327222012.54103-1-andriy.shevchenko@linux.intel.com>

Since we don't use structure field layout randomization
the manual shuffling can affect some macros, in particular
kobj_to_swnode(), which becomes a no-op when kobj member
is the first one in the struct swnode.

Bloat-o-meter statistics:

  add/remove: 0/0 grow/shrink: 2/10 up/down: 9/-100 (-91)
  Total: Before=7217, After=7126, chg -1.26%
