The following commit has been merged into the ras/core branch of tip: Commit-ID: 612905e13b8769caca7ec4194a8aceb24efa4d5c Gitweb: https://git.kernel.org/tip/612905e13b8769caca7ec4194a8aceb24efa4d5c Author: Nikolay Borisov <nik.borisov@suse.com> AuthorDate: Tue, 07 Nov 2023 18:55:29 +02:00 Committer: Borislav Petkov (AMD) <bp@alien8.de> CommitterDate: Wed, 15 Nov 2023 17:19:14 +01:00 x86/mce: Remove redundant check from mce_device_create() mce_device_create() is called only from mce_cpu_online() which in turn will be called iff MCA support is available. That is, at the time of mce_device_create() call it's guaranteed that MCA support is available. No need to duplicate this check so remove it.
