This series converts all existing users of strlcpy in drivers/staging to use strscpy instead.
strlcpy is marked as deprecated in Documentation/process/deprecated.rst, and there is no functional difference when the caller expects truncation (when not checking the return value). strscpy is relatively better as it also avoids scanning the whole source string.
This silences the related checkpatch warnings from: 5dbdb2d87c29 ("checkpatch: prefer strscpy to strlcpy")
The conversions were performed in two steps:
1. The following coccinelle script was used to identify and replace call sites that expect truncation.
$ spatch --sp-file strscpy.cocci --include-headers --dir --in-place drivers/staging
@strscpy@ expression dest, src, size; @@ -strlcpy(dest, src, size); +strscpy(dest, src, size);
2. Each individual automated conversion was rechecked manually for correctness.
