| Subject: powerpc/eeh: Drop redundant spinlock initialization |
| |
| From: Haowen Bai <baihaowen@meizu.com> |
| |
| [ Upstream commit 3def164a5cedad9117859dd4610cae2cc59cb6d2 ] |
| |
| slot_errbuf_lock has declared and initialized by DEFINE_SPINLOCK, |
| so we don't need to spin_lock_init again, drop it. |
