From fe18894930a025617114aa8ca0adbf94d5bffe89 Mon Sep 17 00:00:00 2001 From: Haibo Chen Date: Mon, 25 Apr 2022 16:41:00 +0800 Subject: iio: mma8452: fix probe fail when device tree compatible is used. Correct the logic for the probe. First check of_match_table, if not meet, then check i2c_driver.id_table. If both not meet, then return fail.
