This semantic patch looks for semicolons that can be removed without
changing the semantics of the code. The confidence is moderate
because there are some false positives on cases like:
b/drivers/mmc/host/cb710-mmc.c:589
break;
case MMC_POWER_UP:
default:
- /* ignore */;
}
There are 37 patches accepted reported by this semantic patch and
more than 300 fixes to be applied.
