[PATCH 11/30] ccs: Stop reading arrays after the first zero

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The register arrays have a certain size but not all the entries will be
relevant. In practice reading can be stopped after encountering a zero
value in the array. Do that to avoid extra reads.
