[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 3/5] [media] rc: meson-ir: Fix module autoload

[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/rc/meson-ir.ko | grep alias
$

After this patch:

$ modinfo drivers/media/rc/meson-ir.ko | grep alias
alias:          of:N*T*Camlogic,meson-gxbb-irC*
alias:          of:N*T*Camlogic,meson-gxbb-ir
alias:          of:N*T*Camlogic,meson8b-irC*
alias:          of:N*T*Camlogic,meson8b-ir
alias:          of:N*T*Camlogic,meson6-irC*
alias:          of:N*T*Camlogic,meson6-ir
