[PATCH 0/5] [media] Fix module autoload for media platform drivers

[Javier Martinez Canillas]

Hello Mauro,

I noticed that module autoload won't be working in a bunch of media
platform drivers because the module alias information is not filled
in the modules. This patch series contains the fixes for them.

Best regards,
Javier

[PATCH 1/5] [media] v4l: vsp1: Fix module autoload for OF registration

[Javier Martinez Canillas]

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*
