+Subject: mailbox: imx: fix suspend failue
+To: stable@vger.kernel.org
+Message-ID: <20240412052133.1805029-1-mizo@atmark-techno.com>

+From: Daisuke Mizobuchi <mizo@atmark-techno.com>
+
+When an interrupt occurs, it always wakes up.
+
+Suspend fails as follows:
+ armadillo:~# echo mem > /sys/power/state
+ [ 2614.602432] PM: suspend entry (deep)
+ [ 2614.610640] Filesystems sync: 0.004 seconds
+ [ 2614.618016] Freezing user space processes ... (elapsed 0.001 seconds) done.
+ [ 2614.626555] OOM killer disabled.
+ [ 2614.629792] Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done.
+ [ 2614.638456] printk: Suspending console(s) (use no_console_suspend to debug)
+ [ 2614.649504] PM: Some devices failed to suspend, or early wake event detected
+ [ 2614.730103] PM: resume devices took 0.080 seconds
+ [ 2614.741924] OOM killer enabled.
+ [ 2614.745073] Restarting tasks ... done.
+ [ 2614.754532] PM: suspend exit
+ ash: write error: Resource busy
+ armadillo:~#
+
+Upstream is correct, so it seems to be a mistake in cheery-pick.
