linux-toradex.git/arch/arm/boot/compressed/misc.h, branch v4.19 Linux kernel for Apalis and Colibri modules ARM: decompressor: fix warning introduced in fortify patch 2018-04-05T22:56:40+00:00 Russell King rmk+kernel@armlinux.org.uk 2018-03-29T10:59:17+00:00 5f8d561fb019a3ebe073c019bf5f797f5b06c55e Commit ee333554fed5 ("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE") introduced a new warning: arch/arm/boot/compressed/misc.c: In function 'fortify_panic': arch/arm/boot/compressed/misc.c:167:1: error: 'noreturn' function does return [-Werror] The simple solution would be to make 'error' a noreturn function, but this causes a prototype mismatch as the function is prototyped in several .c files. So, move the function prototype to a new header. There are also a couple of variables that are also declared in several locations. Clean this up while we are here.

Commit ee333554fed5 ("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE")
introduced a new warning:

arch/arm/boot/compressed/misc.c: In function 'fortify_panic':
arch/arm/boot/compressed/misc.c:167:1: error: 'noreturn' function does return [-Werror]

The simple solution would be to make 'error' a noreturn function, but
this causes a prototype mismatch as the function is prototyped in
several .c files.  So, move the function prototype to a new header.

There are also a couple of variables that are also declared in several
locations.  Clean this up while we are here.
