Subject: [PATCH v5 02/20] x86: apic: Move apic_update_irq_cfg() calls to apic_update_vector()
Date: Tue, 29 Apr 2025 11:39:46 +0530	[thread overview]
Message-ID: <20250429061004.205839-3-Neeraj.Upadhyay@amd.com> (raw)
In-Reply-To: <20250429061004.205839-1-Neeraj.Upadhyay@amd.com>

All callers of apic_update_vector() also call apic_update_irq_cfg()
after it. So, simplify code by moving all such apic_update_irq_cfg()
calls to apic_update_vector().

No functional change intended.
