regulator: twl6030: fix range comparison, allowing vsel = 59
The range min_uV > 1350000 && min_uV <= 150000 is never reachable because of a typo in the previous range check and hence vsel = 59 is never reached. Fix the previous range check to enable the vsel = 59 setting. Fixes CoverityScan CID#728454 ("Logially dead code") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Mark Brown <broonie@kernel.org>
