########## File path: drivers/sensors/sensor.c ########## @@ -801,9 +654,9 @@ int sensor_register(FAR struct sensor_lowerhalf_s *lower, int devno) /* Initialize sensor buffer */ - ret = sensor_buffer_create(&upper->buffer, - lower->type, lower->buffer_size); - if (ret) + bytes = ROUNDUP(lower->buffer_size, g_sensor_info[lower->type].esize); Review comment: When fetch is NULL, the lower->buffer_size is zero, and ROUNDUP(lower->buffer_size,...) also is zero, so circ_buffer_init will not alloc buffer space for sensor using fetch api. This ensures code consistency between not fetch and use fetch. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
