Not the final ones, just from first macro expansion of driver
source, that's why I'd like to see changes on w83627hf driver
as I can test it right through.
I haven't looked at your patched source yet to see about applying
it to other drivers, 'cos I'm happy to do that part for you if I
can follow the changes :)

No, I'm not doing a proper compile, I'm intentionally doing partial
compile of driver.c and _not_ including headers, ignoring errors due
to missing headers.
This technique seems valid for the type of testing I'm doing, which
is simply to pull out the first level macro expansion.
Script is work in progress, updated to current version up at:

Not singletons, 3 of each (from an intermediate file):
adm1026.c temp1_crit_enable S_IRUGO S_IWUSR
adm1026.c temp2_crit_enable S_IRUGO S_IWUSR
adm1026.c temp3_crit_enable S_IRUGO S_IWUSR
adm1026.c pwm1 S_IRUGO S_IWUSR
adm1026.c pwm2 S_IRUGO S_IWUSR
adm1026.c pwm3 S_IRUGO S_IWUSR
adm1026.c temp1_auto_point1_pwm S_IRUGO S_IWUSR
adm1026.c temp2_auto_point1_pwm S_IRUGO S_IWUSR
adm1026.c temp3_auto_point1_pwm S_IRUGO S_IWUSR
adm1026.c temp1_auto_point2_pwm S_IRUGO
adm1026.c temp2_auto_point2_pwm S_IRUGO
adm1026.c temp3_auto_point2_pwm S_IRUGO
Yet, in related groups of three you have:
adm1026.c SENSOR_temp1_crit S_IRUGO S_IWUSR
adm1026.c SENSOR_temp2_crit S_IRUGO S_IWUSR
adm1026.c SENSOR_temp3_crit S_IRUGO S_IWUSR

Thank you, what I will do is remove the "SENSOR_" and flag attribute
column with an asterisk to indicate dynamic attribute, something
like that. And flag singletons too.
Thanks,
--Grant.
