Subject: [PATCH v3 3/4] usb: gadget: udc: bcm63xx: Convert to use list_count()
Date: Tue, 22 Nov 2022 17:35:15 +0200	[thread overview]
Message-ID: <20221122153516.52577-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20221122153516.52577-1-andriy.shevchenko@linux.intel.com>

The list API now provides the list_count() to help with counting
existing nodes in the list. Utilise it.
