Different from its predecessor MSM8916, where 'calib_sel' bits sit in separate qfprom word, MSM8939 has 'cailb' and 'calib_sel' bits mixed and spread on discrete offsets. That's why all qfprom bits are read as one go and later mapped to calibration data for MSM8939.

It was created expecting lots of custom routines per version of the TSENS IP. We haven't needed those, there is now only data in the version-specific files. Merge the code for tsens-common.c into tsens.c. As a result, - Remove any unnecessary forward declarations in tsens.h. - Add a Linaro copyright to tsens.c. - Fixup the Makefile to remove tsens-common.c. - Where it made sense, fix some 80-column alignments in the tsens-common.c code being copied over. There is no functional change with this patch.

Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.
