[Buildroot] [PATCH 1/1] support/scripts/apply-patches.sh: handle tar and mkdir failures

[Romain Naour <romain.naour@gmail.com>]

Hi S?bastien,

Le 25/05/2016 ? 14:13, S?bastien Szymanski a ?crit :
> With several archives in a space-separated list of patches, if one archive
> cannot be untar (i.e because it is not readable), Buildroot keeps going instead
> of aborting. Fix this by checking the tar return code.
> While at it, check if the unpack archive directory creation is successful.

I don't see why mkdir can fail here.

Ok with the check.
