Subject: [PATCH] iio: dummy_evgen: modify the return value check for irq_sim_init()
Date: Mon, 27 Nov 2017 11:54:49 +0100	[thread overview]
Message-ID: <20171127105449.27535-1-brgl@bgdev.pl> (raw)

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
users handle the return value of these routines.
