mainline inclusion from mainline-v4.20-rc1 commit 3512dcb4e6c64733871202c01f0ec6b5d84d32ac category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4MKP4 CVE: NA
--------------------------------
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.
