Subject: [PATCH v6 15/15] spmi: pmic-arb: revert "disassociate old virq if hwirq mapping already exists"
Date: Sat, 19 Jan 2019 15:42:52 -0500	[thread overview]
Message-ID: <20190119204252.18370-16-masneyb@onstation.org> (raw)
In-Reply-To: <20190119204252.18370-1-masneyb@onstation.org>

Now that spmi-gpio is a proper hierarchical IRQ chip, and all in-tree
users of device tree have been updated, we can now drop the hack that
was introduced to disassociate the old Linux virq if a hwirq mapping
already exists. That patch was introduced to not break git bisect for
any existing boards.

Driver was tested using gpio-keys and iadc/vadc on the LG Nexus 5
(hammerhead) phone.
