From 042d4460b5b4379a12f375045ff9065cf6758735 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 22 Dec 2015 17:25:17 +0200 Subject: stm class: Select CONFIG_SRCU The newly added STM code uses SRCU, but does not ensure that this code is part of the kernel: drivers/built-in.o: In function `stm_source_link_show': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock' drivers/built-in.o: In function `stm_source_link_drop': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock' This adds a Kconfig 'select' statement like all the other SRCU using drivers have.
