patch "iio:proximity:sx_common: Fix device property parsing on DT systems" added to char-misc-linus

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

iio:proximity:sx_common: Fix device property parsing on DT systems

to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-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:proximity:sx_common: Fix device property parsing on DT systems

After commit 7a3605bef878 ("iio: sx9310: Support ACPI property") we started using the 'indio_dev->dev' to extract device properties for various register settings in sx9310_get_default_reg(). This broke DT based systems because dev_fwnode() used in the device_property*() APIs can't find an 'of_node'. That's because the 'indio_dev->dev.of_node' pointer isn't set until iio_device_register() is called. Set the pointer earlier, next to where the ACPI companion is set, so that the device property APIs work on DT systems.
