Probably not, but afterwards you sent your series which moves the driver 
into drivers/gpio/ and which does the same, so this one was flagged 
"superseeded" in Patchwork 
(https://patchwork.ozlabs.org/project/linuxppc-dev/patch/20260517063754.21819-1-rosenp@xxxxxxxxx/)

I put it back to 'new'. Maddy, can you pick it up ?
