| Subject: [PATCH 111/299] [media] v4l: vsp1: Fix module autoload for OF |
| registration |
| |
| If the driver is built as a module, autoload won't work because the module |
| alias information is not filled. So user-space can't match the registered |
| device with the corresponding module. |
| |
| Export the module alias information using the MODULE_DEVICE_TABLE() macro. |
| |
| Before this patch: |
| |
| $ modinfo drivers/media/platform/vsp1/vsp1.ko | grep alias |
| alias: vsp1 |
| |
| After this patch: |
| |
| $ modinfo drivers/media/platform/vsp1/vsp1.ko | grep alias |
| alias: vsp1 |
| alias: of:N*T*Crenesas,vsp2C* |
| alias: of:N*T*Crenesas,vsp2 |
| alias: of:N*T*Crenesas,vsp1C* |
| alias: of:N*T*Crenesas,vsp1 |
