From 48f703d6a3d7cf345fe9c6209ea3703fe9024628 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 5 Sep 2024 16:28:59 +0300 Subject: [PATCH] power: supply: max1720x: fix a double free on error in probe() In this code, if devm_add_action_or_reset() fails, it will call max1720x_unregister_ancillary() which in turn calls i2c_unregister_device(). Thus the call to i2c_unregister_device() on the following line is not required and is a double unregister. Delete it.
