From bf60e50cb3ed50ae536f7655c8af1acda137ea5b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 18 Feb 2015 20:48:54 +0100 Subject: net/appletalk: LTPC needs virt_to_bus The ltpc driver is rather outdated and does not get built on most platforms because it requires the ISA_DMA_API symbol. However there are some ARM platforms that have ISA_DMA_API but no virt_to_bus, and they get this build error when enabling the ltpc driver. drivers/net/appletalk/ltpc.c: In function 'handlefc': drivers/net/appletalk/ltpc.c:380:2: error: implicit declaration of function 'virt_to_bus' [-Werror=implicit-function-declaration] set_dma_addr(dma,virt_to_bus(ltdmacbuf)); ^ This adds another dependency in Kconfig to avoid that configuration.
