Subject: [PATCH 2/6] irqchip: Make IRQCHIP_MATCH() type safe
Date: Sat, 12 Sep 2020 13:51:44 +0100	[thread overview]
Message-ID: <20200912125148.1271481-3-maz@kernel.org> (raw)
In-Reply-To: <20200912125148.1271481-1-maz@kernel.org>

IRQCHIP_DECLARE() is backed by macros that perform some elementary
type checking on the probe function. Unfortunately, IRQCHIP_MATCH()
doesn't, risking difficult debugging sessions...

Rewrite IRQCHIP_MATCH() in terms of _OF_DECLARE_ELMT() restore
the missing type safety.
