The cover letter [PATCH 0/4] clearly states the origin of these patches.

The sign-off indicates that I am compliant with http://developercertificate.org/, in particular clause b)

I do not take credit for the creation for all of these patches, but I am pushing them.

I apologise if it appears anything was untoward, but I could not find any trace of these patches being pushed elsewhere.

This patch has been in OpenWrt for 6 months which you apparently signed off.

https://dev.openwrt.org/browser/trunk/target/linux/generic/patches-3.18/431-mtd-bcm47xxpart-support-for-Xiaomi-specific-board_da.patch

While true I have not tested this code path, why has this not been raised earlier?

At the very least it does not prevent compilation for other brcm47xx targets.

That does not justify its inclusion however, and I have no issues with this patch being dropped.

Joseph
