Andreas, All,

On 2021-03-09 18:25 +0000, Andreas Ziegler spake thusly:

Not sure why, but your patch ended up completely mangled on Patchwork:
    https://patchwork.ozlabs.org/project/buildroot/patch/539abc1b8ea48daa694b45242cab63d0 at umbiko.net/

Anyway, I fixed it, and moved everything inside a single conditional
block, rather than triplicate the same condition in sequence.

Applied to master, thanks.

Regards,
Yann E. MORIN.
