Various fixes and enhancements for the ak8975 magnetometers family driver. Changes since v1: * get rid of silly le16 to cpu conversion since SMBUS handles this for us when reading words (patch 3/6) * get rid of axes caching and serialize bus access between trigger handler and read_raw * pack triggered buffer sampling bus accesses into a single SMBUS data block access * use channel address within read_raw Changes since v2: * use devm_regulator_get to allow dummy regulator usage * ensure regulator is properly disabled * drop first 3 patches since applied * document in_magn_matrix sysfs attribute * single line comments where appropriate * remove explicit zero init for shift field of iio_chan_spec structure as that's the default * drop unnecessary ak8975_read_axis signature modification * remove useless cosmetic changes related to ak8975_channels * normalize and make error handling code paths clearer * make ak8975_remove less nitpick'able :) Gregor.
