Randy Dunlap faed25ba98 x86/Kconfig: Fix an unused variable error in dell-smm-hwmon 
commit ef775a0e36 upstream.

When CONFIG_PROC_FS is not set, there is a build warning (turned
into an error):

  ../drivers/hwmon/dell-smm-hwmon.c: In function 'i8k_init_procfs':
  ../drivers/hwmon/dell-smm-hwmon.c:624:24: error: unused variable 'data' [-Werror=unused-variable]
    struct dell_smm_data *data = dev_get_drvdata(dev);

Make I8K depend on PROC_FS and HWMON (instead of selecting HWMON -- it
is strongly preferred to not select entire subsystems).

Build tested in all possible combinations of SENSORS_DELL_SMM, I8K, and
PROC_FS.

Fixes: 039ae58503 ("hwmon: Allow to compile dell-smm-hwmon driver without /proc/i8k")

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.
