Subject: [PATCH 2/3] irq/irq_sim: modify the return value check for irq_sim_init()
Date: Sun, 4 Mar 2018 13:10:17 +0100 [thread overview]
Message-ID: <20180304121018.640-3-brgl@bgdev.pl> (raw)
In-Reply-To: <20180304121018.640-1-brgl@bgdev.pl>
As discussed with Marc Zyngier: irq_sim_init() and its devres variant
should return the base of the allocated interrupt range on success
rather than 0. This will be modified later - first, change the way
devm_irq_sim_init() check the return value.
