staging: ion: Fix possible null pointer dereference
The kbuild test robot reported:
drivers/staging/android/ion/ion_system_heap.c:122 alloc_largest_available() error: potential null dereference 'info'. (kmalloc returns null)
Where the pointer returned from kmalloc goes unchecked for failure.
This patch checks the return for NULL, and reworks the logic, as
suggested by Colin, so we allocate the page_info structure first.
