   4 Subject: clk: qcom: mmcc-apq8084: fix terminating of frequency table arrays
   5

   8 [ Upstream commit a903cfd38d8dee7e754fb89fd1bebed99e28003d ]
   9
  10 The frequency table arrays are supposed to be terminated with an
  11 empty element. Add such entry to the end of the arrays where it
  12 is missing in order to avoid possible out-of-bound access when
  13 the table is traversed by functions like qcom_find_freq() or
  14 qcom_find_freq_floor().
  15
  16 Only compile tested.
