[PATCH v2 1/2] iio: proximity: sx_common: Don't use IIO device for properties

From: Andy Shevchenko
Date: Wed Jun 15 2022 - 07:47:59 EST


It's not correct to use artificial device created by IIO core to
retrieve device properties. Even ->get_default_reg() callback
takes a simple struct device pointer which suggests it wants to
operate on the real device.

Correct this by replacing pointer to IIO device by a real device
pointer in the caller of ->get_default_reg().
