Hi Linus,
After merging the gpio tree, today's linux-next build (x86_64 allmodconfig) produced this warning:
drivers/gpio/gpiolib-acpi.c: In function 'acpi_gpiochip_add': drivers/gpio/gpiolib-acpi.c:925:9: warning: 'lflags' may be used uninitialized in this function [-Wmaybe-uninitialized] ret = gpiod_hog(desc, name, lflags, dflags); ^ drivers/gpio/gpiolib-acpi.c:912:16: note: 'lflags' was declared here unsigned int lflags, dflags; ^ drivers/gpio/gpiolib-acpi.c:925:7: warning: 'dflags' may be used uninitialized in this function [-Wmaybe-uninitialized] ret = gpiod_hog(desc, name, lflags, dflags); ^ drivers/gpio/gpiolib-acpi.c:912:24: note: 'dflags' was declared here unsigned int lflags, dflags; ^
These presumably have appeared since -Wmaybe-uninitialized has been reenabled in Linus Torvald's tree.
-- Cheers, Stephen Rothwell
