   9 22e8e19 has introduced a regression in the imgchip->pwm_clk lookup, whereas
  10 the clock name has also been renamed to "imgchip". This causes the driver
  11 failing to load:
  12
  13 [    0.546905] img-pwm 18101300.pwm: failed to get imgchip clock
  14 [    0.553418] img-pwm: probe of 18101300.pwm failed with error -2
  15
  16 Fix this lookup by reverting the clock name back to "pwm".
