Subject: [PATCH] drivers/net/can/Kconfig: Let CAN_AT91 depend on HAS_IOMEM
Date: Thu, 02 Oct 2014 22:01:42 +0800 [thread overview]
Message-ID: <542D5AC6.4010404@gmail.com> (raw)
CAN_AT91 needs HAS_IOMEM, so depends on it. The related error (with
allmodconfig under um):
CC [M] drivers/net/can/at91_can.o
drivers/net/can/at91_can.c: In function ‘at91_can_probe’:
drivers/net/can/at91_can.c:1329:2: error: implicit declaration of function ‘ioremap_nocache’ [-Werror=implicit-function-declaration]
addr = ioremap_nocache(res->start, resource_size(res));
^
drivers/net/can/at91_can.c:1329:7: warning: assignment makes pointer from integer without a cast [enabled by default]
