I think it would be better, if you provide one cover letter as 0/3 patch and three nested real patches to each iio/accel driver which you want to rework: adxl372, bma180, mma8452. Or fix all iio drivers (no only accel) and send all of these changes as nested patches for one cover letter.
Please refer to https://www.kernel.org/doc/html/latest/process/submitting-patches.html
and use the following commands to generate such patches hierarchy:
$ git format-patch --cover-letter -o patches ... $ git send-email \ --annotate \ --to="john.doe@kernel.org" \ --cc="linux-iio@vger.kernel.org" \ --cc="linux-kernel@vger.kernel.org" \ --smtp-debug 1 \ patches/*
