Hi Gwendal, Thank you for the patch! Perhaps something to improve: [auto build test WARNING on iio/togreg] [also build test WARNING on chrome-platform-linux/for-next linus/master v5.7-rc5 next-20200508] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Gwendal-Grignou/iio-cros_ec-Add-support-for-RGB-light-sensor/20200507-074251 base: https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git togreg config: i386-randconfig-a003-20200511 (attached as .config) compiler: gcc-7 (Ubuntu 7.5.0-6ubuntu2) 7.5.0 reproduce: # save the attached .config to linux build tree make ARCH=i386 If you fix the issue, kindly add following tag as appropriate Reported-by: kbuild test robot <lkp@xxxxxxxxx> All warnings (new ones prefixed by >>): drivers/iio/light/cros_ec_light_prox.c:39:40: warning: left-hand operand of comma expression has no effect [-Wunused-value] #define CROS_EC_LIGHT_RGB_SPACE_MASK (6, 4) ^ drivers/iio/light/cros_ec_light_prox.c:51:2: note: in expansion of macro 'CROS_EC_LIGHT_RGB_SPACE_MASK' CROS_EC_LIGHT_RGB_SPACE_MASK, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/iio/light/cros_ec_light_prox.c:39:38: error: initializer element is not constant #define CROS_EC_LIGHT_RGB_SPACE_MASK (6, 4) ^ drivers/iio/light/cros_ec_light_prox.c:51:2: note: in expansion of macro 'CROS_EC_LIGHT_RGB_SPACE_MASK' CROS_EC_LIGHT_RGB_SPACE_MASK, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/iio/light/cros_ec_light_prox.c:39:38: note: (near initialization for 'cros_ec_light_prox_bitmasks[3]') #define CROS_EC_LIGHT_RGB_SPACE_MASK (6, 4) ^ drivers/iio/light/cros_ec_light_prox.c:51:2: note: in expansion of macro 'CROS_EC_LIGHT_RGB_SPACE_MASK' CROS_EC_LIGHT_RGB_SPACE_MASK, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/iio/light/cros_ec_light_prox.c:39:40: warning: left-hand operand of comma expression has no effect [-Wunused-value] #define CROS_EC_LIGHT_RGB_SPACE_MASK (6, 4) ^ drivers/iio/light/cros_ec_light_prox.c:52:2: note: in expansion of macro 'CROS_EC_LIGHT_RGB_SPACE_MASK' CROS_EC_LIGHT_RGB_SPACE_MASK | CROS_EC_LIGHT_CLEAR_OR_PROXIMITY_MASK, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/iio/light/cros_ec_light_prox.c:39:38: error: initializer element is not constant #define CROS_EC_LIGHT_RGB_SPACE_MASK (6, 4) ^ drivers/iio/light/cros_ec_light_prox.c:52:2: note: in expansion of macro 'CROS_EC_LIGHT_RGB_SPACE_MASK' CROS_EC_LIGHT_RGB_SPACE_MASK | CROS_EC_LIGHT_CLEAR_OR_PROXIMITY_MASK, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/iio/light/cros_ec_light_prox.c:39:38: note: (near initialization for 'cros_ec_light_prox_bitmasks[4]') #define CROS_EC_LIGHT_RGB_SPACE_MASK (6, 4) ^ drivers/iio/light/cros_ec_light_prox.c:52:2: note: in expansion of macro 'CROS_EC_LIGHT_RGB_SPACE_MASK' CROS_EC_LIGHT_RGB_SPACE_MASK | CROS_EC_LIGHT_CLEAR_OR_PROXIMITY_MASK, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/dev_printk.h:14:0, from include/linux/device.h:15, from drivers/iio/light/cros_ec_light_prox.c:8: drivers/iio/light/cros_ec_light_prox.c: In function 'cros_ec_light_capture': drivers/iio/light/cros_ec_light_prox.c:39:40: warning: left-hand operand of comma expression has no effect [-Wunused-value] #define CROS_EC_LIGHT_RGB_SPACE_MASK (6, 4) ^ include/linux/compiler.h:58:52: note: in definition of macro '__trace_if_var' #define __trace_if_var(cond) (__builtin_constant_p(cond) ?
