ASoC: nau8810: fix the issue of 64 bits division
Do division with div_u64 for the PLL calculation. These errors are fixed and list as follows: 1."__udivdi3" [sound/soc/codecs/snd-soc-nau8810.ko] undefined! 2."__aeabi_uldivmod" [sound/soc/codecs/snd-soc-nau8810.ko] undefined! 3. nau8810.c:(.text.nau8810_calc_pll+0xd8): undefined reference to `__udivdi3' Signed-off-by: John Hsu <KCHSU0@nuvoton.com> Signed-off-by: Mark Brown <broonie@kernel.org>
