Subject: [PATCH 5.4 210/214] staging: fieldbus: anybuss: jump to correct label in an error path

From: Jing Xiangfeng <jingxiangfeng@...wei.com>

commit 7e97e4cbf30026b49b0145c3bfe06087958382c5 upstream.

In current code, controller_probe() misses to call ida_simple_remove()
in an error path. Jump to correct label to fix it.

Fixes: 17614978ed34 ("staging: fieldbus: anybus-s: support the Arcx anybus controller")
