Message-Id: <20191018004929.3445-6-paul.walmsley@sifive.com> Date: Thu, 17 Oct 2019 17:49:26 -0700 From: Paul Walmsley <paul.walmsley@...ive.com> To: linux-riscv@...ts.infradead.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 5/8] riscv: add missing prototypes sparse identifies these missing prototypes when building arch/riscv: arch/riscv/kernel/cpu.c:149:29: warning: symbol 'cpuinfo_op' was not declared. Should it be static? arch/riscv/kernel/irq.c:27:29: warning: symbol 'do_IRQ' was not declared. Should it be static? arch/riscv/kernel/irq.c:57:13: warning: symbol 'init_IRQ' was not declared.

Should it be static? arch/riscv/kernel/ptrace.c:151:6: warning: symbol 'do_syscall_trace_enter' was not declared. Should it be static? arch/riscv/kernel/ptrace.c:165:6: warning: symbol 'do_syscall_trace_exit' was not declared. Should it be static? Fix by adding the missing prototypes to the appropriate header files. This change should have no functional impact.
