Subject: Is there any way to add an attribute under sysfs at the “platform” level?
Date: Sun, 18 Jun 2017 17:38:36 +0300	[thread overview]
Message-ID: <20170618143836.GA7147@home> (raw)

Hello everybody!

I am trying to modify "pcspkr" driver undere linux kernel source tree. I added a new line there:

sample_id_dir = kobject_create_and_add("devices/platform/pcspkr/sample", NULL);

It works and creates kobject without errors. I checked this in the driver code and in the dmesg output. But "sample" catalog isn't appear under "/sys/devices/platform/pcspkr/".

What is wrong with that code ?

Thanks in advance,
Roman Storozhenko
