Subject: [RFC PATCH 6/6] pinctrl: Check get_group_pins callback on init
Date: Fri, 23 Jul 2021 17:28:58 +0930	[thread overview]
Message-ID: <20210723075858.376378-7-andrew@aj.id.au> (raw)
In-Reply-To: <20210723075858.376378-1-andrew@aj.id.au>

Do configurations exist where this doesn't make sense? I lost some time
to debugging the fact that I was missing the callback :(
