I was not careful enough, sorry. Thanks for fixing it.

Another hunk as follows would also be required for error
path even though compiler didn't complain.

Not sure whether you can fixup or I should post as a
separate patch.

As an aside, there was compiler warning before this
series, but I didn't dare to touch it, so a warning
was seen but thought it was due to the earlier one.
And now Arnd has fixed the original warning.

Regards
Afzal

Oh OK, please just post a separate patch as I've
already pushed it out.

I have posted a separate patch, please consider for
inclusion in your tree.

BTW, you original commit that fixes the compiler
warning has some strange characters.

Ah thanks, that's a copy paste UTF-8 issue. I'll just fold
in the fixes and push them out to a new devel-gpmc-fixed
branch.
