i2c: nvidia-gpu: mark resume function as __maybe_unused

arndb · Wolfram Sang · commit 32774a8153b4 · 2018-12-11T21:39:43.000+01:00
When CONFIG_PM is disabled, this is needed to avoid a harmless unused-function warning: drivers/i2c/busses/i2c-nvidia-gpu.c:345:12: error: 'gpu_i2c_resume' defined but not used [-Werror=unused-function] Fixes: c71bcdc ("i2c: add i2c bus driver for NVIDIA GPU") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
