randconfig build reports the following error which is caused by that CONFIG_PM_OPP is unset. CC arch/arm/mach-imx/mach-imx6q.o arch/arm/mach-imx/mach-imx6q.c: In function ‘imx6q_opp_init’: arch/arm/mach-imx/mach-imx6q.c:248:2: error: implicit declaration of function ‘of_init_opp_table’ [-Werror=implicit-function-declaration] Fix the error by giving a more correct condition for empty of_init_opp_table() implementation.
