[PATCH v2 1/2] Staging: android/ion: fix sparse warnings

[Joseph Wright]

Declare functions to fix sparse warnings:

ion_carveout_heap.c:115:17: warning: symbol 'ion_carveout_heap_create' \
	was not declared. Should it be static?
ion_chunk_heap.c:120:17: warning: symbol 'ion_chunk_heap_create' \
	was not declared. Should it be static?

Hi,

please consider changing your subject to something like

staging: android/ion: declare two functions

Perhaps you can make it more on-topic. It's more useful than "fix
sparse warning"

And then explain why declaring them is preferred over making them static.

[PATCH v2 2/2] Staging: android/ion: fix sparse warning

[Joseph Wright]

Declare private function static to fix sparse warning:

ion_cma_heap.c:109:5: warning: symbol '__ion_add_cma_heaps' \
	was not declared. Should it be static?

Hi,

Again, your subject is too generic.
