Commit5f84bb1a40("soc/tegra: pmc: Add sysfs entries for reset info") added sysfs entries for Tegra reset source and level. However, these sysfs are not removed on error and so if the registering of PMC device is probe deferred, then the next time we attempt to probe the PMC device warnings such as the following will be displayed on boot ... sysfs: cannot create duplicate filename '/devices/platform/7000e400.pmc/reset_reason' Fix this by calling device_remove_file() for each sysfs entry added on failure. Note that we call device_remove_file() unconditionally without checking if the sysfs entry was created in the first place, but this should be OK because kernfs_remove_by_name_ns() will fail silently.

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.
