The following commit has been merged into the x86/irq branch of tip: Commit-ID: 34739a2809e1e5d54d41d93cfc6b074e8d781ee2 Gitweb: https://git.kernel.org/tip/34739a2809e1e5d54d41d93cfc6b074e8d781ee2 Author: Maciej W. Rozycki <macro@xxxxxxxxxxx> AuthorDate: Tue, 20 Jul 2021 05:28:15 +02:00 Committer: Thomas Gleixner <tglx@xxxxxxxxxxxxx> CommitterDate: Tue, 10 Aug 2021 23:31:44 +02:00 x86: Fix typo s/ECLR/ELCR/ for the PIC register The proper spelling for the acronym referring to the Edge/Level Control Register is ELCR rather than ECLR. Adjust references accordingly. No functional change. Signed-off-by: Maciej W.
