gpiolib: Mark gpio_suffixes array with __maybe_unused
[ Upstream commit b23ec59926faf05b0c43680d05671c484e810ac4 ] Since we put static variable to a header file it's copied to each module that includes the header. But not all of them are actually used it. Mark gpio_suffixes array with __maybe_unused to hide a compiler warning: In file included from drivers/gpio/gpiolib-legacy.c:6:0: drivers/gpio/gpiolib.h:95:27: warning: ‘gpio_suffixes’ defined but not used [-Wunused-const-variable=] static const char * const gpio_suffixes[] = { "gpios", "gpio" }; ^~~~~~~~~~~~~ In file included from drivers/gpio/gpiolib-devprop.c:17:0: drivers/gpio/gpiolib.h:95:27: warning: ‘gpio_suffixes’ defined but not used [-Wunused-const-variable=] static const char * const gpio_suffixes[] = { "gpios", "gpio" }; ^~~~~~~~~~~~~ Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
