Subject: [RFC PATCH v7 19/37] x86/apic: Move apic_update_irq_cfg() calls to apic_update_vector()
Date: Tue, 10 Jun 2025 23:24:06 +0530	[thread overview]
Message-ID: <20250610175424.209796-20-Neeraj.Upadhyay@amd.com> (raw)
In-Reply-To: <20250610175424.209796-1-Neeraj.Upadhyay@amd.com>

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

No functional change intended.
