Subject: [PATCH v2 0/3] hwmon: (dell-smm) Improve init code

This patch series improves the init code of the dell_smm_hwmon
driver. The first patch speeds up device initialisation by avoiding
unnecessary SMM calls during init, which might be slow on some
machines. The second patch is a small cleanup patch, while the
third patch allows for easier diagnosis of audio problems caused
by really slow SMM calls.

Tested on a Dell Inspiron 3505.

Changes in v2:
- replace pr_warn() with pr_warn_once()

Armin Wolf (3):
  hwmon: (dell-smm) Avoid unnecessary SMM calls during init
  hwmon: (dell-smm) Cleanup init code
  hwmon: (dell-smm) Warn if SMM call took a very long time to execute
