Subject: [4.4-stable 06/22] idle: i7300: add PCI dependency
Date: Tue, 20 Feb 2018 12:54:53 +0100 [thread overview]
Message-ID: <20180220115527.1806578-7-arnd@arndb.de> (raw)
In-Reply-To: <20180220115527.1806578-1-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.
