+Subject: [PATCH] media: intel/ipu7: psys: register bus before adding the psys
+ device
+
+The psys driver defines a custom "intel-ipu7-psys" bus_type, assigns it
+to the psys device (psys->dev.bus = &ipu7_psys_bus) and then calls
+device_register(), but it never calls bus_register() for that bus.
+
+Older kernels tolerated registering a device on an unregistered bus, but
+since Linux 7.1 bus_add_device() rejects it, so probe fails:
+
+  bus_add_device: cannot add device 'ipu7-psys0' to unregistered bus 'intel-ipu7-psys'
+  intel-ipu7-psys ipu7-psys0: psys device_register failed
+  intel_ipu7_psys.psys intel_ipu7.psys.40: probe with driver intel_ipu7_psys.psys failed with error -22
+
+As a result /dev/ipu7-psys0 is never created and the userspace camera
+HAL cannot open the psys device, breaking the camera on IPU7 platforms
+(e.g. Panther Lake with ov08x40) for every capture application.
+
+Register the bus in module init before registering the auxiliary driver,
+and unregister it on exit, by replacing module_auxiliary_driver() with
+explicit module_init()/module_exit() hooks.
