SubjectRe: [PATCH v2 1/2] extcon: max77843: improve the code and minimize duplicated lines
Hi,

Actually, I checked this patch on following four case.
It is same operation between before and after.
-------------------------------------------------------------
| adc | chg_type |
-------------------------------------------------------------
case 1 | MAX77843_MUIC_ADC_GROUND | MAX77843_MUIC_CHG_NONE |
case 2 | MAX77843_MUIC_ADC_GROUND | |
case 3 | | MAX77843_MUIC_CHG_NONE |
case 4 | | |
-------------------------------------------------------------


But, I don't want to apply this patch.

By applying this patch, I think there is no huge benefits
and certainly I prefer to remain the all descriptions for specific use-case.
(- This patch deletes the 13 lines and add new 8 lines except for the comment.)
