From 0600cf63006688e221e183f1fa480c6ec5975ceb Mon Sep 17 00:00:00 2001 From: Varun Wadekar Date: Mon, 5 Nov 2018 15:12:55 -0800 Subject: tlkd: remove system off/reset handlers TLK does not participate in the system off/reset process and so has no use for the SYSTEM_OFF/RESET notifications. This patch removes the system off/reset handlers as a result.
