From 82e60d920e8ad70cd9a280ab156566755f1fe4aa Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Mon, 5 Nov 2018 14:35:22 +0200 Subject: ath10k: snoc: fix unbalanced clock error handling Similar to regulator error handling, we should only start tearing down the 'i - 1' clock when clock 'i' fails to enable. Otherwise, we might end up with an unbalanced clock, where we never successfully enabled the clock, but we try to disable it anyway.
