5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Randy Dunlap <rdunlap@infradead.org>
[ Upstream commit 19fdc68aa7b90b1d3d600e873a3e050a39e7663d ]
A build with W=1 fails because there are code and data that are not
needed or used when CONFIG_EFI is not set. Move the "#ifdef CONFIG_EFI"
block to earlier in the source file so that the unused code/data are
not built.
