[PATCH v7 0/3] Fixes for Tegra soctherm

[PATCH v7 0/3] Fixes for Tegra soctherm

[Wei Ni]

This series fixed some issues for Tegra soctherm,
and add get_trend().

Main changes from v6:
1. Per Eduardo's comment, we can remove the change:
"thermal: tegra: parse sensor id before sensor register"

Main changes from v5:
1. Move the get_trend() patch https://lkml.org/lkml/2018/11/20/643
into this serial.

Main changes from v4:
1. fixed for the parsing sensor id.
2. keep warning for missing critical trips.

Main changes from v3:
1. updated codes for parsing sensor id, per Thierry's comments

Main changes from v2:
1. add codes to parse sensor id to avoid registration
failure.

Main changes from v1:
1. Acked by Thierry Reding <treding@nvidia.com> for the patch
"thermal: tegra: fix memory allocation".
2. Print out the sensor name when register failed.
2. Remove patch "thermal: tegra: fix coverity defect"

Wei Ni (3):
  thermal: tegra: remove unnecessary warnings
  thermal: tegra: fix memory allocation
  thermal: tegra: add get_trend ops

No need to use the mutex here.

Why not ?

temp = READ_ONCE(tz->temperature);
last_temp = READ_ONCE(tz->last_temperature);

It has been awhile since this patch was submitted and merged by
Eduardo. I replace him to co-maintain the thermal framework with Rui.

While figuring out the internals for code cleanup, I ended up in this
function above.

Why do you have to use this routine instead of the generic one in
get_tz_trend()?
