From: Sean Christopherson Date: Wed, 11 Jun 2025 22:45:33 +0000 (-0700) Subject: KVM: SVM: Clean up return handling in avic_pi_update_irte() X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=803928483669b41e84c27086ffcf28438c1a8cca;p=thirdparty%2Fkernel%2Fstable.git KVM: SVM: Clean up return handling in avic_pi_update_irte() Clean up the return paths for avic_pi_update_irte() now that the refactoring dust has settled. Opportunistically drop the pr_err() on IRTE update failures. Logging that a failure occurred without _any_ context is quite useless.
