[U-Boot] curious snippet in drivers/mtd/dataflash.c

not sure about this bit of code in that source file:

/* Set the environment according to the label...*/ if(protected == FLAG_PROTECT_INVALID) { dataflash_info[i].Device.area_list[j].protected = FLAG_PROTECT_INVALID; } else { dataflash_info[i].Device.area_list[j].protected = protected; }

is that not just setting the value to "protected" in both cases? what is the point of that conditional?
