Subject: [PATCH v2 0/4] kernel.h: find_closest() macro
Date: Tue, 10 Mar 2015 18:27:18 +0100	[thread overview]
Message-ID: <1426008442-26236-1-git-send-email-bgolaszewski@baylibre.com> (raw)

This series proposes to unduplicate the code used to find the
member in an array closest to 'x'.

The first patch adds a macro implementing the algorithm in two
flavors - for arrays sorted in ascending and descending order.
Other three patches replace duplicated code with calls to one
of these macros in some hwmon drivers.

v2:
- fixed an off-by-one bug in patch [3/4]

v1:
https://lkml.org/lkml/2015/2/24/509

Bartosz Golaszewski (4):
  kernel.h: add find_closest() macro
  hwmon: (ina2xx) replace ina226_avg_bits() with find_closest()
  hwmon: (lm85) replace x_TO_REG() functions with find_closest()
  hwmon: (w83795) use find_closest_desc() in pwm_freq_to_reg()
