It is just private chat we discussed about the out-of-bounds array issue. Check patch complained about missing Closes tag. But as per [1], Closes tag report is not required for private bugs?? [1] https://docs.kernel.org/process/submitting-patches.html#using-reported-by-tested-by-reviewed-by-suggested-by-and-fixes I will send next version if it is OK for you without the Closes tag Or Will just remove Reported-by tag to make check patch happy. Please let me know.
