Subject: [v2,1/6] x86/MCE: Make struct mce_banks[] static
Date: Thu, 11 Apr 2019 20:18:00 +0000	[thread overview]
Message-ID: <20190411201743.43195-2-Yazen.Ghannam@amd.com> (raw)

From: Yazen Ghannam <yazen.ghannam@amd.com>

The struct mce_banks[] array is only used in mce/core.c so move the
definition of struct mce_bank to mce/core.c and make the array static.

Also, change the "init" field to bool type.
