+Subject: [PATCH] staging: bcm2835-audio: Add missing MODULE_ALIAS
+
+Commit 8353fe6f1e0f ("Revert "staging: bcm2835-audio: Drop DT
+dependency"") reverts the upstream change and makes bcm2835-audio use
+device tree again, however, it also removes the MODULE_ALIAS for the
+platform device. This MODULE_ALIAS is needed, because VCHIQ registers
+bcm2835-audio as a child platform device since commit 25c7597af20d
+("staging: vchiq_arm: Register a platform device for audio"), and this
+mechanism is adopted also in the downstream kernel.
+
+This commit puts back that MODULE_ALIAS to make bcm2835-audio
+autoprobing work again. The rest of VCHIQ children have their
+MODULE_ALIASes in place.
+
