Edwin Peer d69753fa1e bnxt_en: return proper error codes in bnxt_show_temp
Returning "unknown" as a temperature value violates the hwmon interface
rules. Appropriate error codes should be returned via device_attribute
show instead. These will ultimately be propagated to the user via the
file system interface.

In addition to the corrected error handling, it is an even better idea to
not present the sensor in sysfs at all if it is known that the read will
definitely fail. Given that temp1_input is currently the only sensor
reported, ensure no hwmon registration if TEMP_MONITOR_QUERY is not
supported or if it will fail due to access permissions. Something smarter
may be needed if and when other sensors are added.

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.
