iio: (max1363) Fix probe error pathiio-fixes-for-3.8a
Instantiating the driver with no available regulator results in:
[39711.686393] i2c i2c-7: new_device: Instantiated device max1139 at 0x35
[39711.688687] BUG: unable to handle kernel paging request at fffffffffffffe13
[39711.688734] IP: [<ffffffff813e835b>] regulator_disable+0x1b/0x80
[39711.688788] PGD 1c0e067 PUD 1c0f067 PMD 0
[39711.688835] Oops: 0000 [#1] SMP
Caused by bad probe error path. Fix it.
Driver should also not attempt to free the interrupt in its error path if
none was allocated. Fix that problem as well.
Finally, testing if the regulator was allocated is not necessary in the
remove function, since the probe function bails out if this is the case.
Remove that check.
