[PATCH 01/19] ASoC: da7218: avoid 64-bit compile warning

[PATCH 01/19] ASoC: da7218: avoid 64-bit compile warning

[Arnd Bergmann]

When building the da7218 driver on a 64-bit architecture, we get
a harmless warning:

sound/soc/codecs/da7218.c: In function 'da7218_of_get_id':
sound/soc/codecs/da7218.c:2261:10: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

This changes the code to use uintptr_t to ensure we have an integer
type of the same size as a pointer and won't get a warning on any
architecture.

Please ignore the "[01/19]", I didn't mean to send this as a series, so just
apply it directly. I happen to send 19 patches to different maintainers
and misused git-format-patch.
