+Subject: media: uvcvideo: Fix uvc_alloc_entity() allocation alignment
+
+From: Nadav Amit <namit@vmware.com>
+
+commit 89dd34caf73e28018c58cd193751e41b1f8bdc56 upstream.
+
+The use of ALIGN() in uvc_alloc_entity() is incorrect, since the size of
+(entity->pads) is not a power of two. As a stop-gap, until a better
+solution is adapted, use roundup() instead.
+
+Found by a static assertion. Compile-tested only.
+
+Fixes: 4ffc2d89f38a ("uvcvideo: Register subdevices for each entity")
