From: Arnd Bergmann <arnd@xxxxxxxx>
DIV_ROUND_CLOSEST() does not work on 64-bit variables when building for
a 32-bit target:
ld.lld: error: undefined symbol: __udivdi3
>>> referenced by loongson_i2s.c
>>> sound/soc/loongson/loongson_i2s.o:(loongson_i2s_hw_params) in archive vmlinux.a
Use DIV_ROUND_CLOSEST_ULL() instead.
Fixes: d24028606e764 ("ASoC: loongson: Add Loongson ASoC Sound Card Support")
