Subject[PATCH 4.4 153/193] idle: i7300: add PCI dependency
4.4-stable review patch.  If anyone has any objections, please let me know.


From: Arnd Bergmann <>

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.
