You should have a default. (This is what made Dan less than convinced of whether this was a good change when I originally suggested it) I still think it's a marginal improvement in making it explicit that we only have two valid choices though - and Dan didn't care strongly about it.

Use switch statement instead of if-else pair to explicitly match the only two channels present. Signed-off-by: Himanshu Jha <himanshujha199640@gmail.com> --- drivers/staging/iio/accel/adis16201.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-)
