{ 0 } only clears the first member of the structure.
The first member of the snd_soc_dapm_update struct is a pointer, and writing 0 to a pointer results in the following sparse warning:
sound/soc/codecs/wm9712.c:229:47: warning: Using plain integer as NULL pointer
Use the empty struct initializer that clears all the struct members and fixes the sparse warning.
