Subject: patch "iio: bh1780: dereference the client properly" added to staging-linus
Date: Tue, 07 Jun 2016 22:33:43 -0700	[thread overview]
Message-ID: <14653640233088@kroah.com> (raw)


This is a note to let you know that I've just added the patch titled

    iio: bh1780: dereference the client properly

to my staging git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: iio: bh1780: dereference the client properly

The code in runtime_[suspend|resume] was assuming that the
i2c client data was the bh1780 state container, but it contains
the IIO device. So first dereference the IIO device from the
i2c client, then get the state container using the iio_priv()
call.
