2019-07-08hwmon: (ina3221) Add of_node_put() before returnNishka Dasgupta
Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return. Issue found with Coccinelle.

2019-07-08hwmon: (lm90) Introduce function to update configuration registerGuenter Roeck
The code to update the configuration register is repeated several times. Move it into a separate function. At the same time, un-inline lm90_select_remote_channel() and leave it up to the compiler to decide what to do with it. Also remove the 'client' argument from lm90_select_remote_channel() and from lm90_write_convrate() and take it from struct lm90_data instead where needed. This patch reduces code size by more than 800 bytes on x86_64. Cc: Boyang Yu <byu@arista.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2019-07-08hwmon: (lm90) Cache configuration register valueGuenter Roeck

2019-07-08hwmon: (lm90) Fix max6658 sporadic wrong temperature readingBoyang Yu
max6658 may report unrealistically high temperature during the driver initialization, for which, its overtemp alarm pin also gets asserted. For certain devices implementing overtemp protection based on that pin, it may further trigger a reset to the device. By reproducing the problem, the wrong reading is found to be coincident with changing the conversion rate. To mitigate this issue, set the stop bit before changing the conversion rate and unset it thereafter. After such change, the wrong reading is not reproduced. Apply this change only to the max6657 kind for now, controlled by flag LM90_PAUSE_ON_CONFIG. Signed-off-by: Boyang Yu <byu@arista.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2019-06-23hwmon: (pmbus/adm1275) Fix power sampling supportGuenter Roeck
Not every chip supported by this driver supports setting the number of samples for power averaging. Also, the power monitoring register is not always a 16-bit register, and the configuration bits used for voltage sampling are different depending on the register width. Some conditional code is needed to fix the problem. On top of all that, the compiler complains about problems with FIELD_GET and FIELD_PREP macros if the file is built with W=1. Avoid using those macros to silence the warning.

2019-06-23hwmon: (core) Add comment describing how hwdev is freed in error pathGuenter Roeck
The hwmon core registers the hwmon device before adding sensors to the thermal core. If that fails, the hwmon device is released and an error is returned to the caller. From the code flow, it appears to be necessary to free struct hwmon_device *, allocated with kzalloc(), in that situation. This is incorrect, since the data structure will be freed automatically in hwmon_dev_release() when device_unregister() is called. This used to result in a double free, which was found and fixed with commit 74e3512731bd ("hwmon: (core) Fix double-free in __hwmon_device_register()"). This is, however, not obvious; any reader may erroneously conclude that the data structure is not freed. Add comment explaining why kfree() is not necessary in this situation.

2019-06-23hwmon: (occ) Add temp sensor value checkAlexander Soldatov
The occ driver supports two formats for the temp sensor value. The OCC firmware for P8 supports only the first format, for which no range checking or error processing is performed in the driver. Inspecting the OCC sources for P8 reveals that OCC may send a special value 0xFFFF to indicate that a sensor read timeout has occurred, see https://github.com/open-power/occ/blob/master_p8/src/occ/cmdh/cmdh_fsp_cmds.c#L395 That situation wasn't handled in the driver. This patch adds invalid temp value check for the sensor data format 1 and handles it the same way as it is done for the format 2, where EREMOTEIO is reported for this case.

We don't have anything else outstanding at the moment anyway, and with the summer months on us and people taking trips, I expect the next weeks leading up to the merge window to be pretty calm and sedate. This has two simple, no brainer fixes for the EFA driver. Then it has ten not quite so simple fixes for the hfi1 driver. The problem with them is that they aren't simply one liner typo fixes. They're still fixes, but they're more complex issues like livelock under heavy load where the answer was to change work queue usage and spinlock usage to resolve the problem, or issues with orphaned requests during certain types of failures like link down which required some more complex work to fix too. They all look like legitimate fixes to me, they just aren't small like I wish they were.
