Subject: [PATCH 1/2] mac8390: propagate error code from request_irq
Date: Tue, 1 Jun 2010 22:18:32 +1000 (EST) [thread overview]
Message-ID: <alpine.OSX.2.00.1006011738330.299@localhost> (raw)
In-Reply-To: <20100531.060225.68146363.davem@davemloft.net>
Use the request_irq() error code as the return value for mac8390_open().
EAGAIN doesn't make sense for Nubus slot IRQs. Only this driver can claim
this IRQ (until the NIC is removed, which means everything is powered
down).
