From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: sysctl: add register_sysctl() dummy helper
register_sysctl() has been around for five years with commit fea478d4101a
("sysctl: Add register_sysctl for normal sysctl users") but now that arm64
started using it, I ran into a compile error:
arch/arm64/kernel/armv8_deprecated.c: In function 'register_insn_emulation_sysctl':
arch/arm64/kernel/armv8_deprecated.c:257:2: error: implicit declaration of function 'register_sysctl'
This adds a inline function like we already have for
register_sysctl_paths() and register_sysctl_table().
Link: http://lkml.kernel.org/r/20171106133700.558647-1-arnd@xxxxxxxx
Fixes: 38b9aeb32fa7 ("arm64: Port deprecated instruction emulation to new sysctl interface")
