| Subject: staging: iio: adt7316: allow adt751x to use internal vref for all dacs |
| |
| From: Jeremy Fertic <jeremyfertic@gmail.com> |
| |
| commit 10bfe7cc1739c22f0aa296b39e53f61e9e3f4d99 upstream. |
| |
| With adt7516/7/9, internal vref is available for dacs a and b, dacs c and |
| d, or all dacs. The driver doesn't currently support internal vref for all |
| dacs. Change the else if to an if so both bits are checked rather than |
| just one or the other. |
