[libcamera-devel] [PATCH] libcamera: Fix compilation issue in musl environment

[Kieran Bingham]

Hi Laurent, Madhavan,

Aye aye aye,

I've already submitted such a patch, and it's been reviewed - so I must
not have integrated it yet :-(

https://lists.libcamera.org/pipermail/libcamera-devel/2020-January/006315.html

I'll go check out why it's not yet upstream and make sure something gets
up fast.

Now that this has been reported directly as well I'll add:
"Reported-by: Madhavan Krishnan <madhavan.krishnan at linaro.org>" to my patch.

My previous patch doesn't remove sys/sysmacros. I'll update it to do so,
retest, and repost before integrating.
