      hwmon: (ltc4245) Expose all GPIO pins as analog voltages · 5950ec8d
      由 Ira W. Snyder 提交于 
      Add support for exposing all GPIO pins as analog voltages. Though this is
not an ideal use of the chip, some hardware engineers may decide that the
LTC4245 meets their design requirements when studying the datasheet.

The GPIO pins are sampled in round-robin fashion, meaning that a slow
reader will see stale data. A userspace application can detect this,
because it will get -EAGAIN when reading from a sysfs file which contains
stale data.

Users can choose to use this feature on a per-chip basis by using either
platform data or the OF device tree (where applicable).

      hwmon: (pc87360) Fix device resource declaration · b9783dce
      由 Jean Delvare 提交于 
      It's not OK to call platform_device_add_resources() multiple times
in a row. Despite its name, this functions sets the resources, it
doesn't add them. So we have to prepare an array with all the
resources, and then call platform_device_add_resources() once.

Before this fix, only the last I/O resource would be actually
registered. The other I/O resources were leaked.

      hwmon: (k8temp) Adjust confusing if indentation · df149d02
      由 Julia Lawall 提交于 
      Move the if(err) statement after the if into the if branch indicated by its
indentation.  The preceding if(err) test implies that err cannot be nonzero
unless the if branch is taken.

The semantic match that finds this problem is as follows:
