Hi Darren,
After merging the drivers-x86 tree, today's linux-next build (x86_64 allmodconfig) produced this warning:
In file included from include/linux/kernel.h:13:0, from drivers/platform/x86/thinkpad_acpi.c:52: drivers/platform/x86/thinkpad_acpi.c: In function 'hotkey_init': include/linux/printk.h:299:2: warning: 'type' may be used uninitialized in this function [-Wmaybe-uninitialized] printk(KERN_INFO pr_fmt(fmt), ##__VA_ARGS__) ^ drivers/platform/x86/thinkpad_acpi.c:3147:8: note: 'type' was declared here char *type; ^ In file included from include/linux/kernel.h:13:0, from drivers/platform/x86/thinkpad_acpi.c:52: include/linux/printk.h:299:2: warning: 'in_tablet_mode' may be used uninitialized in this function [-Wmaybe-uninitialized] printk(KERN_INFO pr_fmt(fmt), ##__VA_ARGS__) ^ drivers/platform/x86/thinkpad_acpi.c:3146:6: note: 'in_tablet_mode' was declared here int in_tablet_mode, res; ^
Introduced by commit
b31800283868 ("platform/x86: thinkpad_acpi: Move tablet detection into separate function")
I can't tell if this is a false positive or not.
-- Cheers, Stephen Rothwell
