Subject: [PATCH] most: usb: Use kzalloc_objs for endpoint address array
Date: Wed, 25 Feb 2026 19:03:29 +0100	[thread overview]
Message-ID: <20260225180329.712101-2-thorsten.blum@linux.dev> (raw)

Replace kcalloc() with kzalloc_objs() when allocating the endpoint
address array to keep the size type-safe and match nearby allocations.
Reformat ->busy_urbs allocation to a single line. No functional change.
