    Subject[PATCH 1/4] power: reset: at91-reset: Fix module autoload
    Date
    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/power/reset/at91-reset.ko | grep alias
    $

    After this patch:

    $ modinfo drivers/power/reset/at91-reset.ko | grep alias
    alias: of:N*T*Catmel,sama5d3-rstcC*
    alias: of:N*T*Catmel,sama5d3-rstc
    alias: of:N*T*Catmel,at91sam9g45-rstcC*
    alias: of:N*T*Catmel,at91sam9g45-rstc
    alias: of:N*T*Catmel,at91sam9260-rstcC*
    alias: of:N*T*Catmel,at91sam9260-rstc
    alias: platform:at91-sam9g45-reset
    alias: platform:at91-sam9260-reset
