Subject: [PATCH 5.18 0752/1095] xtensa: iss/network: provide release() callback

From: Max Filippov <jcmvbkbc@...il.com>

[ Upstream commit 8864fb8359682912ee99235db7db916733a1fd7b ]

Provide release() callback for the platform device embedded into struct
iss_net_private and registered in the iss_net_configure so that
platform_device_unregister could be called for it.
