From 2794449576a6024e203eca5cc2c1a3ae33102b8e Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 4 Mar 2019 21:06:51 +0100 Subject: [PATCH] platform/chrome: fix wilco-ec dependencies When CROS_EC_LPC is set to =m, we get a link failure for a builtin wilco-ec module: drivers/platform/chrome/wilco_ec/core.o: In function `wilco_ec_remove': core.c:(.text+0x26): undefined reference to `cros_ec_lpc_mec_destroy' drivers/platform/chrome/wilco_ec/core.o: In function `wilco_ec_probe': core.c:(.text+0x18c): undefined reference to `cros_ec_lpc_mec_init' core.c:(.text+0x224): undefined reference to `cros_ec_lpc_mec_destroy' drivers/platform/chrome/wilco_ec/mailbox.o: In function `wilco_ec_mailbox': mailbox.c:(.text+0x104): undefined reference to `cros_ec_lpc_io_bytes_mec' The problem with the existing CROS_EC_LPC_MEC dependency is that this is only for a 'bool' symbol, so the information about the exported functions being in a module is lost on the way, and we actually have to depend on both CROS_EC_LPC and CROS_EC_LPC_MEC.
