Subject: [PATCH 0/2] driver core: Fixes related to device links
Date: Tue, 12 Feb 2019 13:01:13 +0100 [thread overview]
Message-ID: <5510642.nRbR3bcduN@aspire.rjw.lan> (raw)
Hi Greg at al,
These fix two issues on top of the recent device links material in
driver-core/driver-core-next.
The first one fixes a race condition that may trigger when
__pm_runtime_set_status() is used incorrectly (that is, when it is
called with PM-runtime enabled for the target device and working).
The second one fixes a supplier PM-runtime usage counter imbalance
resulting from adding and removing (e.g. in the error code path) a
stateless device link to it from within the consumer driver's probe
callback.
Please refer to the patch changelogs for details.
Cheers,
Rafael
