Subject: [PATCH 4.9 006/177] Revert "led: core: Fix brightness setting when setting delay_off=0"

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jacek Anaszewski <jacek.anaszewski@...il.com>

This reverts commit 86b9fa2190907f4f550d9d6bf490c5f89ca33836 which was
commit 2b83ff96f51d0b039c4561b9f95c824d7bddb85c upstream.

The commit being reverted has two flaws:
 - it introduces a regression, fixed in the upstream
   commit 7b6af2c53192f1766892ef40c8f48a413509ed72.
 - it has truncated commit message
