[PATCH] iio:potentiostat:lmp91000: solve codestyle WARNINGs and CHECKs

From: Lucas Oshiro
Date: Tue Jan 29 2019 - 13:37:17 EST


Solve most of the checkpatch.pl WARNINGs and CHECKs on lmp9100.c. They
are the following:

lmp91000.c:116: CHECK: Unnecessary parentheses around 'state != channel'
lmp91000.c:116: CHECK: Unnecessary parentheses around 'channel == LMP91000_REG_MODECN_TEMP'
lmp91000.c:214: CHECK: braces {} should be used on all arms of this statement
lmp91000.c:216: CHECK: Unbalanced braces around else statement
lmp91000.c:258: WARNING: line over 80 characters
lmp91000.c:279: CHECK: Please don't use multiple blank lines
