4.19-stable review patch. If anyone has any objections, please let me know.

From: Arnd Bergmann arnd@arndb.de
[ Upstream commit 452d8950db3e839aba1bb13bc5378f4bac11fa04 ]
The rt9455_boost_voltage_values[] array is only used when USB PHY support is enabled, causing a W=1 warning otherwise:
drivers/power/supply/rt9455_charger.c:200:18: error: 'rt9455_boost_voltage_values' defined but not used [-Werror=unused-const-variable=]
Enclose the definition in the same #ifdef as the references to it.
