Subject: [PATCH 06/12] ASoC: Intel: avs: Block IPC channel on suspend
Date: Thu, 7 Jul 2022 14:41:47 +0200 [thread overview]
Message-ID: <20220707124153.1858249-7-cezary.rojewski@intel.com> (raw)
In-Reply-To: <20220707124153.1858249-1-cezary.rojewski@intel.com>
To allow for driver's filesystem interfaces e.g.: debugfs, to be touched
even when the device is asleep, mark IPC-channel as blocked when the
device is suspended. This causes any invocation of said interfaces that
do not toggle PM themselves to gracefully fail with "Operation not
permitted" message.
