Subject: [PATCH AUTOSEL 5.2 36/59] arm64/efi: fix variable 'si' set but not used
Date: Tue,  6 Aug 2019 17:32:56 -0400	[thread overview]
Message-ID: <20190806213319.19203-36-sashal@kernel.org> (raw)
In-Reply-To: <20190806213319.19203-1-sashal@kernel.org>

From: Qian Cai <cai@lca.pw>

[ Upstream commit f1d4836201543e88ebe70237e67938168d5fab19 ]

GCC throws out this warning on arm64.

drivers/firmware/efi/libstub/arm-stub.c: In function 'efi_entry':
drivers/firmware/efi/libstub/arm-stub.c:132:22: warning: variable 'si'
set but not used [-Wunused-but-set-variable]

Fix it by making free_screen_info() a static inline function.
