Subject: Re: [PATCH v4 2/2] drivers: bus: Delete CONFIG_SIMPLE_PM_BUS
Date: Thu, 21 Oct 2021 16:51:04 +0530	[thread overview]
Message-ID: <CAMi1Hd0HvPOT277mx8hNTU9NQH2ti7h5qc5+rxOkRWwbfrhyQQ@mail.gmail.com> (raw)

Hi Saravana,

This patch broke v5.15-rc6 on RB5 (sm8250 | qcom/qrb5165-rb5.dts).
I can't boot past this point https://www.irccloud.com/pastebin/raw/Nv6ZwHmW.

Regards,
Amit Pundir
