Three update suggestions were taken into account
from static source code analysis.

Markus Elfring (3):
  Use devm_kcalloc() in ti_bandgap_build()
  Delete error messages for failed memory allocations in ti_bandgap_build()
  Fix a typo in a comment line

[PATCH 1/3] ti-soc-thermal: Use devm_kcalloc() in ti_bandgap_build()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 26 Apr 2017 16:45:25 +0200

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "devm_kcalloc".

This issue was detected by using the Coccinelle software.

[PATCH 2/3] ti-soc-thermal: Delete error messages for failed memory allocations in ti_bandgap_build()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>

The script "checkpatch.pl" pointed information out like the following.

WARNING: Possible unnecessary 'out of memory' message

Thus remove such statements here.

Keerthy,

Can you please give it a shot of this series on all supported OMAP chip
boards? I do not see any major issue with the series at all, but would
like to get it tested by you.

BR,
