Subject: [PATCH] crypto: qat - change value of default idle filter
Git-commit: 0f942bdfe9d463be3073301519492f8d53c6b2d5
Patch-mainline: v6.6-rc1
References: PED-6401
The power management configuration of 4xxx devices is too aggressive
and in some conditions the device might be prematurely put to a low
power state.
Increase the idle filter value to prevent that.
In future, this will be set by firmware.
Fixes: e5745f34113b ("crypto: qat - enable power management for QAT GEN4")
