4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann arnd@arndb.de
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.
