Subject: xtensa: ISS: add comment about etherdev freeing
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c44e783e0b4539cb8296da9229202a9f9e6a3c8d;p=linux.git

xtensa: ISS: add comment about etherdev freeing

iss_net_configure explicitly frees etherdev in all error return paths
except one where register_netdevice fails. In that remaining error
return path the etherdev is freed by the iss_net_pdev_release callback
triggered by the platform_device_unregister call. Add a comment stating
that.
