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.
|
|
