Subject: [PATCH 1/2] alpha: marvel: Fix irq_set_status_flags to use correct IRQ number
Date: Thu, 28 May 2026 19:05:15 -0400 [thread overview]
Message-ID: <20260528230516.1839694-1-mattst88@gmail.com> (raw)
Pass base + i to irq_set_status_flags() to match the IRQ number
used in irq_set_chip_and_handler(). Previously, IRQ_LEVEL was set
on the wrong (low-numbered) IRQ descriptors rather than the IO7
IRQs at base + i.
Cc: stable@vger.kernel.org
Fixes: 08876fe8519c ("alpha: marvel: Convert irq_chip functions")
