Subject: [PATCH 1/1] x86/mce: remove unused WARN_ON() in mce_register_decode_chain()
Date: Fri, 6 Nov 2020 16:43:40 +0800	[thread overview]
Message-ID: <20201106084340.2009-1-thunder.leizhen@huawei.com> (raw)

enum mce_notifier_prios {
        MCE_PRIO_LOWEST,
        MCE_PRIO_MCELOG,
        MCE_PRIO_EDAC,

After commit c9c6d216ed28 ("x86/mce: Rename "first" function as "early""),
there is no other integer between MCE_PRIO_MCELOG and MCE_PRIO_EDAC.
Therefore, the WARN_ON() will never be triggered, just delete it.
