[PATCH 5.4 366/658] powerpc/eeh: Drop redundant spinlock initialization

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Haowen Bai <baihaowen@xxxxxxxxx>

[ 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.
