pdev is a bad name for a global variable. Still more as the driver has functions where pdev is a local variable. Rename it to smsc47m1_pdev. Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

As described in the added code comment, a reference to .exit.text is ok for drivers registered via module_platform_driver_probe(). Make this explicit to prevent the following section mismatch warning WARNING: modpost: drivers/hwmon/smsc47m1: section mismatch in reference: smsc47m1_driver+0x8 (section: .data) -> smsc47m1_remove (section: .exit.text) that triggers on an allmodconfig W=1 build.

Added custom channel-specific (temp1) attribute for resolution. The wait time for a conversion in one-shot mode (enable = 0) depends on the resolution. When resolution is 12-bit, the conversion time is 140ms, but the minimum update_interval is 125ms. Handled this problem by waiting an additional 15ms (125ms + 15ms = 140ms). Added 'mask' parameter to the shutdown_write() function. Now it can either write or update bits, depending on the value of mask. This is needed, because for alarms a write is necessary, but for resolution only the resolution bits should be updated. Signed-off-by:

Some Dell machines like the Dell Optiplex 7000 do not support the legacy SMM interface, but instead expect all SMM calls to be issued over a special WMI interface. Add support for this interface so users can control the fans on those machines. Tested-by: <serverror@serverror.com> Reviewed-by:

In the future, multiple SMM calling backends will exist, with each backend being required to initialize its data. Introduce a helper function for this so the code necessary to initialize dell_smm_data is not duplicated between different backends. Tested-by: <serverror@serverror.com> Reviewed-by:

Currently, i8k_dmi_table contains both entries used for DMI matching and entries used to override config options. This does not allow for differentiating between "its safe to issue raw SMM calls on this machine" and "its not safe to issue raw SMM calls on this machine, but here are some config values". Since future SMM backends will need to differentiate between those two cases, move those config entries into a separate table. i8k_dmi_table now serves as a general "its safe to issue raw SMM calls" table.

Modern Dell machines support multiple ways to issue an SMM call. Prepare support for those by introducing dell_smm_ops, which is used by dell_smm_call() to perform a SMM call. Each SMM backend needs to provide a dell_smm_ops structure. Tested-by: <serverror@serverror.com> Reviewed-by:

The EliteDesk 800 G6 stores a raw WMI string within the ACPI object in its BIOS corresponding to one instance of HPBIOS_PlatformEvents.Name. This is evidently a valid way of representing a WMI data item as far as the Microsoft ACPI-WMI mapper is concerned, but is preventing the driver from loading. This seems quite rare, but add support for such strings. Treating this as a quirk pretty much means adding that support anyway. Also clean up an oversight in update_numeric_sensor_from_wobj() in which the result of hp_wmi_strdup() was being used without error checking. Reported-by:

The PECI CPU sensors are available as soon as the CPU is powered, however the PECI DIMM sensors are available after DRAM has been trained and thresholds have been written by host firmware. The default timeout of 30 seconds isn't enough for modern multisocket platforms utilizing DDR5 memory to bring up the memory and enable PECI sensor data. Bump the default timeout to 10 minutes in case the system starts without cached DDR5 training data. Signed-off-by:

This attribute is defined as read-only by all drivers that support it. It seems that the access rights and description for this attribute were copied from the intrusionY_alarm, which has indeed RW rights and must be cleared by the user.

Preliminary step to add the missing humidity attributes in the ABI documentation. Adding new elements alphabetically is a common practice that has been loosely followed in the sysfs-class-hwmon documentation. Since most of the humidity attributes must be added to the file, a single attribute needs to be rearranged to reinforce alphabetical order. Signed-off-by:
