Subject: [PATCH net-next 0/6] net: ipa: add a driver shutdown callback
Date: Thu, 19 Nov 2020 16:49:23 -0600 [thread overview]
Message-ID: <20201119224929.23819-1-elder@linaro.org> (raw)
The final patch in this series adds a driver shutdown callback for
the IPA driver. The patches leading up to that address some issues
encountered while ensuring that callback worked as expected:
- The first just reports a little more information when channels
or event rings are in unexpected states
- The second patch recognizes a condition where an as-yet-unused
channel does not require a reset during teardown
- The third patch explicitly ignores a certain error condition,
because it can't be avoided, and is harmless if it occurs
- The fourth properly handles requests to retry a channel HALT
request
- The fifth makes a second attempt to stop modem activity during
shutdown if it's busy
The shutdown callback is implemented by calling the existing remove
callback function (reporting if that returns an error).
