![]() In pflash_write() Coverity points out that we can decrement the unsigned pfl->counter below zero, which makes it wrap around. In fact this is harmless, because if pfl->counter is 0 at this point we also increment pfl->wcycle to 3, and the wcycle == 3 handling doesn't look at counter; the only way back into code which looks at the counter value is via wcycle == 1, which will reinitialize the counter. But it's arguably a little clearer to break early in the "counter == 0" if(), to avoid the decrement-below-zero.
