#1289416 — [PATCH v2 0/2] modify the number of masters

sw_end represents the last software master, sw_start is index of the
first master, so the number of software masters should be
sw_end - sw_start + 1.

This patchset simply modified the similar issue in two modules.

Changes since V1:
* Split the only one patch of V1 into two separated patches according
  to Alex's comments

Chunyan Zhang (2):
  stm: the number of masters should be (sw_end - sw_start + 1)
  intel_th: the number of masters should be (sw_end - sw_start + 1)
