Subject: [PATCH net-next 6/8] pds_core: Don't assign interrupt index/bound_intr to notifyq
Date: Thu, 4 Jan 2024 09:12:19 -0800 [thread overview]
Message-ID: <20240104171221.31399-7-brett.creeley@amd.com> (raw)
In-Reply-To: <20240104171221.31399-1-brett.creeley@amd.com>
The notifyq rides on the adminq's interrupt, so there's
no need to setup and/or access the notifyq's interrupt
index or bound_intr. The driver sets the bound_intr
using qcq->intx = -1 for the notifyq, but luckily
nothing accesses that field for notifyq. Instead of
expecting that remains the case, just clean up
the notifyq's interrupt index and bound_intr fields.
