Browse Source 
commit 9ad63986c6
"pda_power: Add support for using otg transceiver events"
introduces below build error if !CONFIG_USB_OTG_UTILS.

  CC      drivers/power/pda_power.o
drivers/power/pda_power.c: In function 'pda_power_probe':
drivers/power/pda_power.c:322: error: 'otg_is_usb_online' undeclared (first use in this function)
drivers/power/pda_power.c:322: error: (Each undeclared identifier is reported only once
drivers/power/pda_power.c:322: error: for each function it appears in.)
drivers/power/pda_power.c:325: error: 'otg_is_ac_online' undeclared (first use in this function)
drivers/power/pda_power.c:371: error: 'otg_handle_notification' undeclared (first use in this function)
make[2]: *** [drivers/power/pda_power.o] Error 1
make[1]: *** [drivers/power] Error 2
make: *** [drivers] Error 2

This patch adds #ifdef CONFIG_USB_OTG_UTILS guards at necessary places to fix
build errors.
