GCC correctly points out an uninitialized variable use when CONFIG_PCI is disabled.
drivers/idle/i7300_idle.c: In function 'i7300_idle_notifier':
include/asm-generic/bug.h:119:5: error: 'got_ctl' may be used uninitialized in this function [-Werror=maybe-uninitialized]
if (unlikely(__ret_warn_once && !__warned)) { \
^
drivers/idle/i7300_idle.c:415:5: note: 'got_ctl' was declared here
u8 got_ctl;
^~~~~~~
The driver no longer exists in later kernels, so this patch only appplies to
linux-4.9.y and earlier.

Enable memory power savings when idle with certain Intel server

chipsets. The chipset must have I/O AT support, such as the
|
|
Intel 7300. The power savings depends on the type and quantity of
|

DRAM devices.
