Hi all,
After merging the kspp-gustavo tree, today's linux-next build (x86_64
allmodconfig) produced this warning:
In function 'aspeed_create_fan_tach_channel',
inlined from 'aspeed_create_fan' at drivers/hwmon/aspeed-pwm-tacho.c:877:2,
inlined from 'aspeed_pwm_tacho_probe' at drivers/hwmon/aspeed-pwm-tacho.c:936:9:
drivers/hwmon/aspeed-pwm-tacho.c:751:49: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=]

drivers/hwmon/aspeed-pwm-tacho.c: In function 'aspeed_pwm_tacho_probe':

Exposed by commit
1b56c90018f0 ("Makefile: Enable -Wstringop-overflow globally")
This is with your tree on top of Linus' tree (and some fix patches but
nothing that obviously touches anything relevent) and CONFIG_WERROR
not set.
