FP with unreachable code check

[Harshit Mogalapalli <harshit.m.mogalapalli@xxxxxxxxxx>]

Hi Dan,


I think iio_device_claim_direct_scoped() needs special handling, for 
some reason smatch thinks all these calls are not reachable.

drivers/iio/adc/ad7380.c:371 ad7380_debugfs_reg_access() warn: ignoring 
unreachable code.
drivers/iio/adc/ad7380.c:500 ad7380_read_raw() warn: ignoring 
unreachable code.
drivers/iio/adc/ad7380.c:589 ad7380_write_raw() warn: ignoring 
unreachable code.
drivers/iio/adc/ad7606.c:153 ad7606_read_raw() warn: ignoring 
unreachable code.



Thanks,
Harshit
