   4 Subject: [PATCH] clk: Add our request boundaries in
   5  clk_core_init_rate_req
   6
   7 The expectation is that a new clk_rate_request is initialized through a
   8 call to clk_core_init_rate_req().
   9
  10 However, at the moment it only fills the parent rate and clk_hw pointer,
  11 but omits the other fields such as the clock rate boundaries.
  12
  13 Some users of that function will update them after calling it, but most
  14 don't.
  15
  16 As we are passed the clk_core pointer, we have access to those
  17 boundaries in clk_core_init_rate_req() however, so let's just fill it
  18 there and remove it from the few callers that do it right.
