Zev Weiss f4e6960f4f hwmon: (nct6775) Fix platform driver suspend regression
Commit c3963bc0a0 ("hwmon: (nct6775) Split core and platform
driver") introduced a slight change in nct6775_suspend() in order to
avoid an otherwise-needless symbol export for nct6775_update_device(),
replacing a call to that function with a simple dev_get_drvdata()
instead.

As it turns out, there is no guarantee that nct6775_update_device()
is ever called prior to suspend. If this happens, the resume function
ends up writing bad data into the various chip registers, which results
in a crash shortly after resume.

To fix the problem, just add the symbol export and return to using
nct6775_update_device() as was employed previously.
