soundwire: cadence: use u32p_replace_bits
FIELD_PREP() does not replace the bits so it is not apt in case where we modify a register. Use u32p_replace_bits() instead. Fixes: 3cf25d63b1b9 ("soundwire: cadence: use FIELD_{GET|PREP}") Tested-by: Bard Liao <yung-chuan.liao@linux.intel.com> Link: https://lore.kernel.org/r/20200917120146.1780323-2-vkoul@kernel.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
