      hwmon: (lm90) Make code more readable · b2589ab0
      由 Jean Delvare 提交于 
      Clean up the code to make it more readable:
* Remove reg_ and new_ prefixes from variable names, they made the
  names longer, causing extra line breaks, while not adding much
  value.
* Introduce struct device dev* = &client->dev in two functions, to
  avoid repeating client->dev everywhere in these functions.

      hwmon: (lm90) Fix warnings · 8dc089d6
      由 Jean Delvare 提交于 
      With some configuration option combinations, we get the following
warnings:

drivers/hwmon/lm90.c: In function 'lm90_detect':
drivers/hwmon/lm90.c:1114: warning: 'chip_id' may be used uninitialized
in this function
drivers/hwmon/lm90.c:1114: warning: 'reg_config1' may be used
uninitialized in this function
drivers/hwmon/lm90.c:1114: warning: 'reg_convrate' may be used
uninitialized in this function
drivers/hwmon/lm90.c:1187: warning: 'reg_emerg2' may be used
uninitialized in this function
drivers/hwmon/lm90.c:1187: warning: 'reg_status2' may be used
uninitialized in this function

We can solve these easily by reading the register values first and
checking for errors later. These errors should be very rare, even in
the case of failed detection, so this change has no impact on
performance. And this makes checkpatch.pl happier.

      hwmon: (lm90) Add support for the LM99 16 degree offset · 97ae60bb
      由 Jean Delvare 提交于 
      The LM99 differs from the LM86, LM89 and LM90 in that it reports
remote temperatures (temp2) 16 degrees lower than they really are. So
far we have been cheating and handled this in userspace but it really
should be handled by the driver directly.

      hwmon: (lm90) Fix handling of hysteresis value · ec38fa2b
      由 Jean Delvare 提交于 
      There are several problems in the way the hysteresis value is handled
by the lm90 driver:

* In show_temphyst(), specific handling of the MAX6646 is missing, so
  the hysteresis is reported incorrectly if the critical temperature
  is over 127 degrees C.
* In set_temphyst(), the new hysteresis register value is written to
  the chip but data->temp_hyst isn't updated accordingly, so there is
  a short period of time (up to 2 seconds) where the old hystereris
  value will be returned while the new one is already active.
* In set_temphyst(), the critical temperature which is used as a base
  to compute the value of the hysteresis register lacks
  device-specific handling. As a result, the value of the hysteresis
  register might be incorrect for the ADT7461 and MAX6646 chips.

Fix these 3 bugs.
