I did clk_enable -> clk_prepare_enable conversion, as described in another email.
I got occasional error reading:
root@n900:~# cat /sys/class/hwmon/hwmon0/device/temp_input 20.0 root@n900:~# cat /sys/class/hwmon/hwmon0/device/temp_input cat: /sys/class/hwmon/hwmon0/device/temp_input: Input/output error root@n900:~# cat /sys/class/hwmon/hwmon0/device/temp_input 20.0
Nothing in dmesg. It takes few tries to reproduce..
On other attempt, it hung hard:
root@n900:~# cat /sys/class/hwmon/hwmon0/device/temp_input ; cat /sys/class/hwmon/hwmon0/device/temp_input ;cat /sys/class/hwmon/hwmon0/device/temp_input ; cat /sys/class/hwmon/hwmon0/device/temp_input 17.0 17.0 ^[[A
^Z
^C^C^C
