| Subject: [PATCH 057/299] [media] v4l: rcar-fcp: 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/rcar-fcp.ko | grep alias |
| alias: rcar-fcp |
| |
| After this patch: |
| |
| $ modinfo drivers/media/platform/rcar-fcp.ko | grep alias |
| alias: rcar-fcp |
| alias: of:N*T*Crenesas,fcpvC* |
| alias: of:N*T*Crenesas,fcpv |
| alias: of:N*T*Crenesas,fcpfC* |
| alias: of:N*T*Crenesas,fcpf |
