From f1794fd7bdf7981e21595d0162ab4f7305b3c7c1 Mon Sep 17 00:00:00 2001 From: Mircea Caprioru Date: Tue, 25 Jun 2019 11:11:24 +0300 Subject: iio: adc: ad7124: Remove input number limitation The driver limits the user to use only 4/8 differential inputs, but this device has the option to use pseudo-differential channels. This will increase the number of channels to be equal with the number of inputs so 8 channels for ad7124-4 and 16 for ad7124-8. This patch removes the check between channel nodes and num_inputs value.
