  * @brief Array holding one pre-initialized mutex for each I2C device
-static mutex_t locks[] = {
-#if I2C_0_EN
-    [I2C_0] = MUTEX_INIT,
-#if I2C_1_EN
-    [I2C_1] = MUTEX_INIT,
-#if I2C_2_EN
-    [I2C_2] = MUTEX_INIT
-#if I2C_3_EN
-    [I2C_3] = MUTEX_INIT
+static mutex_t locks[I2C_NUMOF];

It's a good options, but I think this syntax is only GCC compliant
