Could use atomic_t for counter protect?
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.
I like the suggestion to use atomic_t. atomic_read() can be used in the
sysfs show method.
Thanks,
Bart.
