'rid' is declared as unsigned int, so there is little point checking for <0.

Removing these checks fixes the following W=1 warnings:

 drivers/regulator/tps65218-regulator.c: In function ‘tps65218_pmic_set_suspend_enable’:
 drivers/regulator/tps65218-regulator.c:131:10: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
 131 | if (rid < TPS65218_DCDC_1 || rid > TPS65218_LDO_1)
 | ^
 drivers/regulator/tps65218-regulator.c: In function ‘tps65218_pmic_set_suspend_disable’:
 drivers/regulator/tps65218-regulator.c:144:10: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
 144 | if (rid < TPS65218_DCDC_1 || rid > TPS65218_LDO_1)
 | ^
