Paul Cercueil 831919b4c4 power/supply: ingenic-battery: Don't change scale if there's only one ... commit 86b9182df8 upstream. The ADC in the JZ4740 can work either in high-precision mode with a 2.5V range, or in low-precision mode with a 7.5V range. The code in place in this driver will select the proper scale according to the maximum voltage of the battery. The JZ4770 however only has one mode, with a 6.6V range. If only one scale is available, there's no need to change it (and nothing to change it to), and trying to do so will fail with -EINVAL. Fixes: fb24ccfbe1 ("power: supply: add Ingenic JZ47xx battery driver.")
