[PATCH] ARM: OMAP3: Beagle: fix return value check in beagle_opp_init()

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

In case of error, the function get_cpu_device() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.
