![]() A problem about insmod thunderbolt-net failed is triggered with following
log given while lsmod does not show thunderbolt_net:
insmod: ERROR: could not insert module thunderbolt-net.ko: File exists
The reason is that tbnet_init() returns tb_register_service_driver()
directly without checking its return value, if tb_register_service_driver()
failed, it returns without removing property directory, resulting the
property directory can never be created later.
tbnet_init()
tb_register_property_dir() # register property directory
tb_register_service_driver()
driver_register()
bus_add_driver()
priv = kzalloc(...) # OOM happened
# return without remove property directory
Fix by remove property directory when tb_register_service_driver() returns
error.
Fixes:

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.
