/opt/ltp/runltp -f fs -s read_all_sys or read_all -d /sys -q -r 10 Or just simply visit the sys node "QCOM8002's pinconf-groups": "cat /sys/kernel/debug/pinctrl/QCOM8002\:00/pinconf-groups" Yanjiang Jin (1): pinctrl: core: make sure strcmp() doesn't get a null parameter drivers/pinctrl/core.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) -- 1.8.3.1 This email is intended only for the named addressee.
