fpga: mgr: altera-ps-spi: make array dummy static, shrinks object size
Don't populate the const array dummy on the stack but instead make it static. Makes the object code smaller by 26 bytes: Before: text data bss dec hex filename 7371 2032 0 9403 24bb drivers/fpga/altera-ps-spi.o After: text data bss dec hex filename 7281 2096 0 9377 24a1 drivers/fpga/altera-ps-spi.o (gcc version 8.2.0 x86_64) Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Alan Tull <atull@kernel.org> Acked-by: Moritz Fischer <mdf@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
