From b3fce99a57377673eaf7c89ae9a42f4fd60966e2 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Thu, 10 Sep 2020 18:32:33 +0100 Subject: [PATCH] iio:chemical:vz89x: Drop of_match_ptr protection and use generic fw accessors This change allow the driver to be used with ACPI PRP0001 and removes an antipattern that I want to avoid being copied into new IIO drivers. The handling of match_data uses a different approach as device_get_match_data() doesn't distinguish between no match, and a match but with NULL data.
