There are 3 times where number and description should match.
For this UFS pin on sm6350 only 2/3 match.
2x the number is 156, 1x it's 163

$ grep -i ufs_reset drivers/pinctrl/qcom/pinctrl-sm6350.c
        PINCTRL_PIN(163, "UFS_RESET"),
static const unsigned int ufs_reset_pins[] = { 156 };
        [156] = UFS_RESET(ufs_reset, 0xae000),

Does that help?

Luca
