Subject: PM / OPP: fix condition for empty of_init_opp_table()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

randconfig build reports the following error which is caused by
CONFIG_PM_OPP being 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.

Subject: imx6q-cpufreq: fix return value check in imx6q_cpufreq_probe()

In case of error, the function devm_regulator_get() returns
ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().
