kstrtol() and friends can return -EINVAL or -ERANGE. We have to test for both, otherwise the value is possibly uninitialized. Also in some of these files we accidentally return "count" on error instead of a negative error code.

According to Documentation/filesystems/sysfs.rst, the show() callback function of kobject attributes should strictly use sysfs_emit() instead of sprintf() family functions. So, make this change. Issue identified using the coccinelle device_attr_show.cocci script. Signed-off-by: Deepak R Varma <drv at mailo.com> --- Note: Resending the patch for review and feedback. No functional changes.

Sorry for that. I'll split the patch and I'll come again ;) El dia 11/04/2017 22:12, "Karol Herbst" <karolherbst at gmail.com> va escriure: thanks for the work, but could you please split that patch? It looks like you are doing several things at once and it isn't really easy to review like this. And it isn't bisectable. If there are clean ups here, please do it

Hi, this patch replaces the old hwmon_device_register with the new hwmon_device_register_with_info. I've tested it on my laptop with a GeForceGT 425M and it doesn't break anything. --- linux/drivers/gpu/drm/nouveau/nouveau_hwmon.c.orig 2017-04-11 18:27:15.477623009 +0200 +++ linux/drivers/gpu/drm/nouveau/nouveau_hwmon.c 2017-04-11 18:45:41.918688215 +0200 @@ -1,5 +1,6 @@ /* - *

Here is where most of the work is being done. We are replacing the old API with the new one, that means changing the functions layout and remove unnecessary code. We also set up the other operations: .read .write .read_string --- linux/drivers/gpu/drm/nouveau/nouveau_hwmon.c.orig 2017-04-13 10:11:29.241000086 +0200 +++ linux/drivers/gpu/drm/nouveau/nouveau_hwmon.c 2017-04-13 10:12:38.016055129

This patch removes old code related to the old api and transforms the functions for the new api. It also adds the .write and .read operations.

A NV34 GPU was seeing temp and pwm entries in hwmon, which would error out when read. These should not have been visible, but also the whole hwmon object should just not have been registered in the first place.

This patch introduces the nouveau_hwmon_ops structure, sets up .is_visible and .read_string operations and adds all the functions for these operations. This is also a preparation for the next patches, where most of the work is being done. This code doesn't interacture with the old one. It's just to make easier the review of all patches. --- drivers/gpu/drm/nouveau/nouveau_hwmon.c | 166
