   4 Subject: [PATCH] clk: Add missing clk_core_init_rate_req calls
   5
   6 Some callers of clk_core_round_rate_nolock() will initialize the
   7 clk_rate_request structure by hand, missing a few parameters that leads
   8 to inconsistencies in what drivers can expect from that structure.
   9
  10 Let's use clk_core_init_rate_req() everywhere to make sure it's built in
  11 a consistent manner.
