Hi!
show me a proof that its copy & paste. because its not
I don't have to prove you anything. Sorry.
then i will deny your argument because its false.
But you said:
see ath9k. its exact the same implementation.
We don't want to have exact same code multiple times in the tree.
it isnt the exact same code, its just the way its done. i mean
registering a led driver function happens multiple times in the kernel
you cannot say that calling led_classdev_register with the required
parameters and function implementation is a case of code duplication.
then i would just say using of "printk" is a case of code duplication.
registering a led driver is nothing unusual, the implementation of the
led driver is different each time. the implementation for led_brightness
is very different
there are many led drivers in the kernel. all are going the same way.
i checked the kernel drivers just right now. almost all major wireless
drivers are comming with a led driver without using gpiolib
your way is a case of codebloating since a registering gpio-leds
requires a gpio driver for each wireless driver, even if its sometimes
just a single register write for a led and no real gpio.
a gpio driver is more complex and bigger than just a led driver. i just
wrote a optional gpio driver to get access to all gpios available on the
card. some vendors are using these in a unusual way
i have seen that vendors used them for reset button input etc. this is
why i made it. so dont take this as a argument for going a impossible
way (again. the kernel does not support multiple platform datas with the
same name
THE KERNEL not leds-gpio. so once a leds-gpio platform data is
registered, no other driver can register a new one.
in addition the kernel must have gpiolib support which increases the
kernel size. the best way is always the most simple way and the smallest
performant way.
and again. i did not duplicate the code of ath9k, i just used it as
documentation to write a own led driver in a simple way
now a list of wireless drivers with a led driver
