Subject: [PATCH] crypto: ccp: Remove forward declaration
Date:   Mon, 24 Sep 2018 10:26:15 -0700

Clang emits a warning about this construct:

drivers/crypto/ccp/sp-platform.c:36:36: warning: tentative array
definition assumed to have one element
static const struct acpi_device_id sp_acpi_match[];
                                   ^
1 warning generated.

Just remove the forward declarations and move the initializations up
so that they can be used in sp_get_of_version and sp_get_acpi_version.
