On NOMMU kernels, the io_desc variables are unused because we don't use the MMU to remap the MMIO areas. Marking these variables as __maybe_unused easily avoids the otherwise harmless warnings like warning: 'versatile_io_desc' defined but not used Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Linus Walleij <redacted> Cc: Russell King <redacted> --- arch/arm/mach-integrator/integrator_ap.c | 2 +- arch/arm/mach-integrator/integrator_cp.c | 2 +- arch/arm/mach-versatile/core.c | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-)
