Subject: [PATCH] genirq: Tell that early_irq_init() is printing the nr of preallocated irqs
Date: Tue, 9 May 2017 10:34:09 +0200 [thread overview]
Message-ID: <1494318849-6733-1-git-send-email-vincent.legoll@gmail.com> (raw)
In-Reply-To: <1494318042-6512-1-git-send-email-vincent.legoll@gmail.com>
The early_irq_init() function was not telling what all the displayed
information is.
- Add some missing whitespace & commas for easier reading
- Tell that the third number is the number of preallocated irqs
returned by arch_probe_nr_irqs()
- Also cover !CONFIG_SPARSE_IRQ case
