From b677b8850322b210a81b72ffcc7de85a3df395c5 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 8 May 2014 10:27:54 +0200 Subject: [PATCH] mmc: rtsx: fix possible linking error if built-in rtsx_usb_sdmmc module uses the LED classdev if available, but the code failed to consider the situation that it is built-in and the LED classdev is a module, leading to following linking error: LD init/built-in.o drivers/built-in.o: In function `rtsx_usb_sdmmc_drv_remove': rtsx_usb_sdmmc.c:(.text+0x2a018e): undefined reference to `led_classdev_unregister' drivers/built-in.o: In function `rtsx_usb_sdmmc_drv_probe': rtsx_usb_sdmmc.c:(.text+0x2a197e): undefined reference to `led_classdev_register' Fix by excluding such condition when defining macro RTSX_USB_USE_LEDS_CLASS.
