[ Upstream commite5da06b27f] The normal call sequence of using transport class is: Add path: transport_setup_device() transport_setup_classdev() // call sas_host_setup() here transport_add_device() // if fails, need call transport_destroy_device() transport_configure_device() Remove path: transport_remove_device() transport_remove_classdev // call sas_host_remove() here transport_destroy_device() If transport_add_device() fails, need call transport_destroy_device() to free memory, but in this case, ->remove() is not called, and the resources allocated in ->setup() are leaked. So fix these leaks by calling ->remove() in transport_add_class_device() if it returns error.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
