[media] ir-sony-decoder: shutup smatch warnings
There are some false-positive warnings produced by smatch: drivers/media/rc/ir-sony-decoder.c:129 ir_sony_decode() warn: missing break? reassigning 'data->state' drivers/media/rc/ir-sony-decoder.c:137 ir_sony_decode() warn: missing break? reassigning 'data->state' drivers/media/rc/ir-sony-decoder.c:165 ir_sony_decode() warn: missing break? reassigning 'data->state' This is due to the logic used there to detect the need of a break. While those are false positives, it is easy to get rid of them without any drawbacks. The side effect is a cleaner function, with is good.
