Subject: ARM: OMAP2+: PM: fix return value check in omap2_set_init_voltage()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=93b44bea0c17130e62d8b1b82c0e2a0d671230d1;p=linux-beck.git

ARM: OMAP2+: PM: fix return value check in omap2_set_init_voltage()

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