Make the line lengths more balanced. Refer to the functions
as simply as func().

  devm_mux_state_get() is called twice in a row. The second call's result
  is stored directly into st->mux_st[AD4134_DOUT0_INPUT] without error
  checking, and then immediately overwritten by the first call's result.

  Remove the duplicate call and check the return value before saving the
  state.

Otherwise it looks like a rebase error which went unnoticed as
the mux state is stored after the check.
