Subject: [PATCH] riscv/vdso: fix missing vdso_data declaration
Date: Wed, 13 Jul 2022 23:06:45 +0100	[thread overview]
Message-ID: <20220713220645.105138-1-ben.dooks@sifive.com> (raw)

The vdso_data is defined by has no declaration as the
arch/riscv/kernel/vdso.c does not include asm/vdso/vsyscall.h
for the definition. Fix the following sparse warning by
adding in the asm/vdso/vsyscall.h

arch/riscv/kernel/vdso.c:42:18: warning: symbol 'vdso_data' was not declared. Should it be static?
