Subject: [PATCH 6/8] openriac: Remove unused nommu_dump_state function
Date: Mon, 21 Aug 2023 08:20:05 +0100 [thread overview]
Message-ID: <20230821072007.2698186-7-shorne@gmail.com> (raw)
In-Reply-To: <20230821072007.2698186-1-shorne@gmail.com>
When compiling with W=1 enabling -Wmissing-prototypes the compiler
warns:
arch/openrisc/kernel/traps.c:146:6: error: no previous prototype for 'nommu_dump_state' [-Werror=missing-prototypes]
This function is not used so remove it.
Reported-by: Arnd Bergmann <arnd@arndb.de>
Closes: https://lore.kernel.org/linux-kernel/20230810141947.1236730-17-arnd@kernel.org/
