[PATCH 4.4 150/193] power: bq27xxx_battery: mark some symbols __maybe_unused

[Greg Kroah-Hartman]

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

Without the I2C driver, we get a few warnings:

drivers/power/bq27xxx_battery.c:288:12: error: 'bq27xxx_regs' defined but not 
used [-Werror=unused-variable]
 static u8 *bq27xxx_regs[] = {
^
drivers/power/bq27xxx_battery.c:994:12: error: 'bq27xxx_powersupply_init' 
defined but not used [-Werror=unused-function]
 static int bq27xxx_powersupply_init(struct bq27xxx_device_info *di,
^
drivers/power/bq27xxx_battery.c:1029:13: error: 
'bq27xxx_powersupply_unregister' defined but not used [-Werror=unused-function]
 static void bq27xxx_powersupply_unregister(struct bq27xxx_device_info *di)
 ^

In mainline kernels, this was addressed by a larger rework in 703df6c09795 
("power:
bq27xxx_battery: Reorganize I2C into a module"). We probably don't want this 
backported
into stable kernels, so instead let's shut up the warnings by marking the 
symbols
as __maybe_unused.
