Subject[PATCH AUTOSEL 5.13 67/85] drivers/perf: fix the missed ida_simple_remove() in ddr_perf_probe()
Date
From: Jing Xiangfeng <jingxiangfeng@huawei.com>

[ Upstream commit d96b1b8c9f79b6bb234a31c80972a6f422079376 ]

ddr_perf_probe() misses to call ida_simple_remove() in an error path.
Jump to cpuhp_state_err to fix it.
