In this if-else conditional statement, if (chan < 16), but
(data[0] == INSN_CONFIG_DIO_QUERY), the function does not return early,
but the else-branch does not get executed either. As a result, mask
would be used uninitialized in the next line. What we want here is if

Update the R-Car Generation 2 PCI driver Kconfig dependencies
