Subject: gpio: mockup: modify the return value check for devm_irq_sim_init()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1e0dca677b9c780e90e708ac3f884c54dba94b18;p=linux.git

gpio: mockup: modify the return value check for devm_irq_sim_init()

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.
