[PATCH -next] extcon: ptn5150: Fix return value check in ptn5150_i2c_probe()

[Wei Yongjun]

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

Fixes: 58963276749e ("extcon: Add support for ptn5150 extcon driver")
