4.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: raveendra padasalagi <raveendra.padasalagi@xxxxxxxxxxxx> commit efc856edfd66acc5da34fec92d7feca6fd0f9add upstream. SPU driver is dependent on generic MAILBOX API's to communicate with underlying DMA engine driver. So this patch removes BCM_PDC_MBOX "depends on" for SPU driver in Kconfig and adds MAILBOX as dependent module.
