Hi Greg, Since [1] hasn't yet found its way to char-misc tree, I'm re-sending it with a few additions, namely: there is one more Kconfig fix from Arnd and two PCI IDs that I'm hoping we could also include in this cycle. Based on char-misc-linus.

Add a dependency on HAS_DMA to fix this.

From: Arnd Bergmann <arnd@arndb.de>
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.
