From: Paul Marques Mota <paul@xxxxxxxxxxxxxx> To: HARDWARE MONITORING <linux-hwmon@xxxxxxxxxxxxxxx> Date: Thu, 7 Dec 2017 20:04:22 +0000 Subject: [PATCH] add stack trace to deprecated hwmon_device_register() Hi, hwmon_device_register() in drivers/hwmon/hwmon.c prints the unhelpful message below on my machine: (NULL device *): hwmon_device_register() is deprecated. Please convert the driver to use hwmon_device_register_with_info(). Therefore, this patch dumps the stack at that point. In my case it is then obvious in the resulting dmesg, available at http://www.marquesmota.pt/dmesg.txt that thermal_add_hwmon_sysfs() in drivers/thermal/thermal_hwmon.c needs to be converted to the new API. This patch is against 4.15.0-rc2 I believe it is also needed in Bugzilla bug #195843 https://bugzilla.kernel.org/show_bug.cgi?id=195843 Signed-off-by: Paul Marques Mota<paul@xxxxxxxxxxxxxx> --- drivers/hwmon/hwmon.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/hwmon/hwmon.c b/drivers/hwmon/hwmon.c index c9790e2c3440..31719ce4a681 100644 --- a/drivers/hwmon/hwmon.c +++ b/drivers/hwmon/hwmon.c @@ -702,6 +702,7 @@ struct device *hwmon_device_register(struct device *dev) { dev_warn(dev, "hwmon_device_register() is deprecated.
