Hi Peter,
Are you suggesting to convert the dev_lvl_exception_count type from u32 
to atomic_t type? Because the value of dev_lvl_exception_count is 
returned to the user space via the device_lvl_exception_count_show() 
using the sysfs_emit() function, keeping the dev_lvl_exception_count as 
u32 data type probably works better in terms of the format.

Thanks, Bao
