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

iio: inkern: fix a NULL dereference on error

to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git

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.

Subject: iio: inkern: fix a NULL dereference on error

In twl4030_bci_probe() there are some failure paths where we call iio_channel_release() with a NULL pointer. (Apparently, that driver can opperate without a valid channel pointer). Let's fix it by adding a NULL check in iio_channel_release().
