From 1dd0d7fe4b7a50f3a9580e994060e8a8a1c3263e Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 27 Jul 2021 13:23:39 +0300 Subject: crypto: omap-sham - drop pm_runtime_irqsafe() usage Commit b0a3d8986a76 ("crypto: omap-sham - Use pm_runtime_irq_safe()") added the use of pm_runtime_irq_safe() as pm_runtime_get_sync() was called from a tasklet. We now use the crypto engine queue instead of a custom queue since commit 33c3d434d91 ("crypto: omap-sham - convert to use crypto engine"). We want to drop the use of pm_runtime_irq_safe() in general as it takes a permanent usage count on the parent device causing issues for power management. Based on testing with CONFIG_DEBUG_ATOMIC_SLEEP=y, modprobe omap-sham, followed by modprobe tcrypt sec=1 mode=423, I have not been able to reproduce the scheduling while atomic issue seen earlier with current kernels and we can just drop the call to pm_runtime_irq_safe().
