I'm seeing a bunch of new errors when running with this patch applied on
top of 6.11-rc1. I'm assuming it is due to changes in timing that are
either exposing existing bugs or there is a general problem with the
in-kernel pd-mapper implementation.

In any case, this does does not seem to be specific to x1e80100 even if
I'm not seeing as many issues on sc8280xp (there is one new error there
too however).

It doesn't happen on every boot, but with the in-kernel pd-mapper I
often (every 3-4 boots) see the following errors on the x1e80100 CRD
during boot:

	[    9.799719] pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to send altmode request: 0x10 (-125)
        [    9.812446] pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to request altmode notifications: -125
        [    9.831796] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI read request: -125

	[    9.269230] qcom_battmgr.pmic_glink_power_supply pmic_glink.power-supply.0: failed to request power notifications

I've also seen the following, which may also be related:

	[   14.565059] PDR: avs/audio get domain list txn wait failed: -110
        [   14.571943] PDR: service lookup for avs/audio failed: -110

I haven't seen the -ECANCELED (-125) errors in 30 reboots with the patch
reverted again.

I once saw

	power_supply qcom-battmgr-bat: driver failed to report `status' property: -110

on the Lenovo ThinkPad X13s which may or may not be related.
