+Subject: [PATCH] spa: libcamera: use `CameraConfiguration::orientation`
+
+libcamera commit cc65629b68d49d ("libcamera: camera: Introduce Orientation") [0]
+introduced to the `CameraConfiguration::orientation` member to describe the
+orientation of the image in the received memory buffers.
+
+Then c65e40b8480ffb ("libcamera: Use CameraConfiguration::orientation") [1]
+removed `CameraConfiguration::transform`, which broke the libcamera plugin.
+
+Fix that by using the new `orientation` member.
