Subject: ARM: OMAP: fix return value check in realtime_counter_init()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=533b298110475804b15b93475389736140bf4aa9;p=linux-beck.git

ARM: OMAP: fix return value check in realtime_counter_init()

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