To: Linux Kernel Mailing List
As late as Friday, I was planning on talking about how nice it is to
see this new trend of tiny rc2 releases, because there really hadn't
been very many pull requests at all.
But it turns out the pull requests were just heavily skewed to the end
of the week, and 4.5-rc2 isn't particularly small after all. It pretty
much doubled over the weekend.
Not that it's all that big anyway, and skewing towards the end of the
week probably makes sense for rc2 - it takes some time to start
finding the problems that the merge window has brought with it. So
this odd behavior doesn't worry me, it seems fairly natural.
As to the kinds of patches we have here: the appended shortlog gives
more details, but it's pretty much all over. Drivers and architecture
updates are only about half of the patch, with perf fixes and some of
the new virtio self-tests being much of the rest. There's some btrfs
fixes too.
None of it is all that big, though.
Go forth and test,
Linus

Fix[1] is already queued by Jani Nikula, I suspect it simply missed the
boat because there was no drm-intel-fixes merge in -rc2.

The bug is also reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=110751
This patch fixes the problem (both for me and others):
From: Martin Wilck <Martin.Wilck@ts.fujitsu.com>
Since b8b2c7d845d5, platform_drv_probe() is called for all platform
devices. If drv->probe is NULL, and dev_pm_domain_attach() fails,
platform_drv_probe() will return the error code from dev_pm_domain_attach().
This causes real_probe() to enter the "probe_failed" path and set
dev->driver to NULL. Before b8b2c7d845d5, real_probe() would assume
success if both dev->bus->probe and drv->probe were missing. As a result,
a device and driver could be "bound" together just by matching their names;
this doesn't work any more after b8b2c7d845d5.
This change broke the assumptions of certain drivers; for example, the TPM
code has long assumed that platform driver and device with matching name
could be bound in this way. That assumption may cause such drivers to
fail with Oops during initialization after applying this change. Failure
in suspend/resume tests under qemu has also been reported.
This patch restores the previous (4.3.0 and earlier) behavior of
platform_drv_probe() in the case when the associated platform driver has
no "probe" function.
Fixes: b8b2c7d845d5 ("base/platform: assert that dev_pm_domain callbacks are called unconditionally")

The patch you show below is included in 4.5-rc2, it's commit
25cad69f21f5532d99e2ee73c8ab6512bcab614c. So how could you apply it to
4.5-rc2 and have this fix the issue for you?

You're right, my bad! In fact, I tested 4.4.1-rc1 and 4.5-rc1.
Sorry for the noise!
