Subject: iio: imu: adis: remove bits_per_word = 8
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=6a1ebdb8a352bfdd53e726a15827a5d0485bad0f;p=linux-2.6-microblaze.git

iio: imu: adis: remove bits_per_word = 8

Remove setting bits_per_word = 8 from the adis driver. This is the
default value for SPI transfers, so it is not necessary to explicitly
set it.
