Subject: [PATCH] firmware: stratix10-svc: add missing gen_pool_destroy() in
 stratix10_svc_drv_probe()
References: bsc#1012628
Patch-mainline: 6.2.3
Git-commit: 9175ee1a99d57ec07d66ff572e1d5a724477ab37

[ Upstream commit 9175ee1a99d57ec07d66ff572e1d5a724477ab37 ]

In error path in stratix10_svc_drv_probe(), gen_pool_destroy() should be called
to destroy the memory pool that created by svc_create_memory_pool().
