* hwmon: (ltc2992) Fix memory leak in ltc2992_parse_dt()Javier Carrasco2024-05-301-1/+3
| | | | | | | | | | | | | | | A new error path was added to the fwnode_for_each_available_node() loop in ltc2992_parse_dt(), which leads to an early return that requires a call to fwnode_handle_put() to avoid a memory leak in that case. Add the missing fwnode_handle_put() in the error path from a zero value shunt resistor.

There is an issue that the PWM signal recorded by oscilloscope would not be on consistently if we set PWM to 100% to the driver. It is because the LSB of the 9 bit would always be zero if it just left shift 8 bit for the value that write to PWMOUT Target Duty Cycle register. Therefore, revise the scale of the value that was written to pwm input from 255 to 511 and modify the value to left-justified value.

The actual update does the following: 1) Lock the memory, but does not perform a SIO entry (previously it would have performed an SIO entry). 2) Attempt to read the chipID. This should be safe no matter which chip we have. 3) If step (2) fails, then perform SIO entry and retry chipID read. For older chips and on failure it acts similarly to prior to this patch. 4) Set the sio_data->type, similar to previously. 5) If we have not performed an SIO entry, and this is not a chip type with the NOCONF feature, then it will perform an SIO entry at this point. 6) Proceed with setup as prior to this patch. 7) Any following access to the SIO registers will invoke the SIO entry and SIO exit steps unless it is a chip with the NOCONF feature set. This was set up in the previous patches in this patchset. 8) Update to the exit based on if it had performed a SIO entry or not.

Bit 23 is specified as reserved. In recent processors, however, the temperature digital readout uses bits [23:16]. In those processors, using the bitmask 0x7f would lead to incorrect readings if the temperature deviates from TjMax by more than 127 degrees Celsius. Although not guaranteed, bit 23 is likely to be 0 in processors from a few generations ago. The temperature reading would still be correct in those processors when using a 0xff bitmask. Model-specific provisions can be made for older processors in which bit 23 is not 0 should the need arise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
