[PULL REQUEST] i2c for 3.13

[PULL REQUEST] i2c for 3.13

[Wolfram Sang]

[-- Attachment #1: Type: text/plain, Size: 8224 bytes --]

Linus,

here is the pull request from the i2c subsystem for 3.13:

* new drivers for exynos5, bcm kona, and st micro
* bigger overhauls for drivers mxs and rcar
* typical driver bugfixes, cleanups, improvements
* got rid of the superfluous 'driver' member in i2c_client struct
  This touches a few drivers in other subsystems. All acked.

There is one conflict because of the INIT_COMPLETION to
reinit_completion rename. linux-next has a proper fix.

The topmost patch has not been in linux-next, yet it is trivial and a
bugfix which I wanted to have in this request. All the rest has
linux-next coverage.

Please pull.

Thanks,

   Wolfram

Re: [PULL REQUEST] i2c for 3.13

So while resolving some fairly trivial conflicts here, I noticed that
commit a76e9bd89ae7 ("i2c: attach/detach I2C client device to the ACPI
power domain") that I got earlier through the ACPI/PM tree calls
acpi_dev_pm_detach() even when the device "->remove()" function fails.
But it only sets clientdata to NULL if it succeeds.

That looks a bit odd.

I didn't try to fix it, though. I just thought I'd point out the oddity.

Well, given that the driver core doesn't even check the return value of
dev->bus->remove(dev), I think doing the unconditional acpi_dev_pm_detach()
is actually correct and clientdata should be cleared unconditionally too.

Actually, can we remove the whole clientdata setting there?

Commit 0998d0631001 (device-core: Ensure drvdata = NULL when no driver is
bound) modified the driver core to always clear out that field. Same seems
to apply if driver probe fails.

Oh, nice, missed that commit. That indeed should help cleaning up the i2c
core a little. I will prepare something.
