[ 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.

[ Upstream commit 2df70149e73e79783bcbc7db4fa51ecef0e2022c ]
The bq27xxx i2c-client may not have an IRQ, in which case
client->irq will be 0. bq27xxx_battery_i2c_probe() already has
an if (client->irq) check wrapping the request_threaded_irq().
But bq27xxx_battery_i2c_remove() unconditionally calls
free_irq(client->irq) leading to:
[ 190.310742] ------------[ cut here ]------------
[ 190.310843] Trying to free already-free IRQ 0
[ 190.310861] WARNING: CPU: 2 PID: 1304 at kernel/irq/manage.c:1893 free_irq+0x1b8/0x310
Followed by a backtrace when unbinding the driver. Add
an if (client->irq) to bq27xxx_battery_i2c_remove() mirroring
probe() to fix this.

RRT_ALRT register holds remaining battery time in minutes therefore it
needs to be scaled accordingly when exposing TIME_TO_EMPTY via sysfs
expressed in seconds
