Subject: [PATCH v3 0/2] Fix simple-bus issues with fw_devlink
Date: Fri, 3 Sep 2021 17:05:40 -0700 [thread overview]
Message-ID: <20210904000543.2019010-1-saravanak@google.com> (raw)
Ulf reported an issue[1] with fw_devlink. This series tries to fix that
issue.
I replicated a similar set up on my end and I confirmed:
- A simple-bus only device is probed.
- Another device listing simple-bus as a 2nd compatible string isn't
probed.
Ulf, mind testing this?
v1->v2:
- Switched to probing the simple-bus device instead of marking it as
NEVER_PROBES.
v2->v3:
- Moved all the code into the simple-pm-bus driver
- Addressed Ulf's comment about the remove() code missing a check.
Thanks,
Saravana
