Subject: [PATCH v2 35/46] scsi: pm8001: Switch to attribute groups
Date: Thu,  7 Oct 2021 14:18:41 -0700	[thread overview]
Message-ID: <20211007211852.256007-36-bvanassche@acm.org> (raw)
In-Reply-To: <20211007211852.256007-1-bvanassche@acm.org>

struct device supports attribute groups directly but does not support
struct device_attribute directly. Hence switch to attribute groups.
