Subject: [PATCH v3 1/2] irq: make irq_domain_reset_irq_data() available even for non-V2 users
Date: Fri, 17 Apr 2020 10:05:48 +0200	[thread overview]
Message-ID: <20200417080549.23751-2-brgl@bgdev.pl> (raw)
In-Reply-To: <20200417080549.23751-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

irq_domain_reset_irq_data() doesn't modify the parent data, so it can be
made available even if irq domain hierarchy is not being built. We'll
subsequently use it in irq_sim code.
