[hijacking the thread since it has the right Cc list already, sorry]

I stumbled over this doing randconfig builds on linux-next

Subject: [PATCH] mmc: rtsx: usb backend needs LED support

Building the rtsx USB driver requires the LED classdev base
support, otherwise we get this build error:

drivers/built-in.o: In function `rtsx_usb_sdmmc_drv_remove':
:(.text+0x806480): undefined reference to `led_classdev_unregister'
drivers/built-in.o: In function `rtsx_usb_sdmmc_drv_probe':
:(.text+0x806708): undefined reference to `led_classdev_register'

This adds an explicit dependency in Kconfig
