2015-05-05	util_macros.h: have array pointer point to array of constants	Guenter Roeck
	Using the new find_closest() macro can result in the following sparse warnings. drivers/hwmon/lm85.c:194:16: warning: incorrect type in initializer (different modifiers) drivers/hwmon/lm85.c:194:16: expected int __fc_a drivers/hwmon/lm85.c:194:16: got int static const [toplevel] <noident> drivers/hwmon/lm85.c:210:16: warning: incorrect type in initializer (different modifiers) drivers/hwmon/lm85.c:210:16: expected int __fc_a drivers/hwmon/lm85.c:210:16: got int const map This is because the array passed to find_closest() will typically be declared as array of constants, but the macro declares a non-constant pointer to it.

2015-04-17	util_macros.h: add find_closest() macro	Bartosz Golaszewski
	This series unduplicates 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. The second updates Documentation/CodingStyle on the naming convention for local variables in macros resembling functions. Other three patches replace duplicated code with calls to one of these macros in some hwmon drivers. This patch (of 5): Searching for the member of an array closest to 'x' is duplicated in several places. Add a new include - util_macros.h - and two macros that implement this algorithm for arrays sorted both in ascending and descending order. Uses linear search.
