__initdata tag should be placed between the variable name and equal
sign for the variable to be placed in the intended .init.data section.

In this particular case __initdata is incorrect as ape6evm_keys_pdata
can be used as a platform data for gpio-keys driver which can be
compiled as module.

Hi Bartlomiej,

Thank you for the patch.

A pointer to the ape6evm_keys_pdata structure is passed to the 
platform_device_register_data() function, which makes a copy of the structure. 
Marking it as __initdata is thus correct.

Thanks for catching this. I'll fix the patch and post v2.
