From ffd46e7f2b87a873bd18db946d61e3466f3ca82f Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 27 Nov 2025 14:43:51 +0100 Subject: [PATCH] hwmon: (max6697) fix regmap leak on probe failure commit 02f0ad8e8de8cf5344f8f0fa26d9529b8339da47 upstream. The i2c regmap allocated during probe is never freed. Switch to using the device managed allocator so that the regmap is released on probe failures (e.g. probe deferral) and on driver unbind.
