driver already supports a 1-wire interface, but this driver uses the
|
||||
same serial logic to implement a lower half driver much like the I2C
|
||||
lower half driver. From Aleksandr Vyhovanec (2015-05-25).
|
||||
* fs/: Add logic to detach a file structure from a file descriptor.
|
||||
This is for use only within the OS. It permits an open file or driver
|
||||
to be used across multiple threads (2016-05-26).

* This function will fail if fd is not a valid file descriptor. In

* Input Parameters:

* fd - The file descriptor to be detached. This descriptor will be
