MIPS: TXx9: use IS_BUILTIN() for CONFIG_LEDS_CLASS
[ Upstream commit 0cde5b44a30f1daaef1c34e08191239dc63271c4 ] When commit b27311e1cace ("MIPS: TXx9: Add RBTX4939 board support") added board support for the RBTX4939, it added a call to led_classdev_register even if the LED class is built as a module. Built-in arch code cannot call module code directly like this. Commit b33b44073734 ("MIPS: TXX9: use IS_ENABLED() macro") subsequently changed the inclusion of this code to a single check that CONFIG_LEDS_CLASS is either builtin or a module, but the same issue remains. This leads to MIPS allmodconfig builds failing when CONFIG_MACH_TX49XX=y is set: arch/mips/txx9/rbtx4939/setup.o: In function `rbtx4939_led_probe': setup.c:(.init.text+0xc0): undefined reference to `of_led_classdev_register' make: *** [Makefile:999: vmlinux] Error 1 Fix this by using the IS_BUILTIN() macro instead.
