Subject: [PATCH] bus: ti-sysc: Remove unpaired sysc_clkdm_deny_idle()
Date: Fri, 6 Sep 2019 13:01:54 -0700 [thread overview]
Message-ID: <20190906200154.6510-1-tony@atomide.com> (raw)
Commit d098913a10f8 ("bus: ti-sysc: Fix clock handling for no-idle
quirks") fixed handling for no-idle quirk modules that are not enabled
by the bootloader.
But it also caused unpaired clockdomain calls that won't allow idling
the system. That's because clkdm_allow_idle_nolock() and
clkdm_deny_idle_nolock() have usage count with clkdm->forcewake_count.
Let's drop the unpaired sysc_clkdm_deny_idle() to fix idling of devices.
