6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
[ Upstream commit 66c5e98bbf7b7b2ba0a095ef25bf55c7230e846e ]
A recent rework accidentally lost the dependency on LEDS_CLASS, which
leads to a link error when LED support is disbled:
x86_64-linux-ld: drivers/leds/simple/simatic-ipc-leds.o: in function `simatic_ipc_leds_probe':
simatic-ipc-leds.c:(.text+0x10c): undefined reference to `devm_led_classdev_register_ext'
Add back the dependency that was there originally.
Fixes: a6c80bec3c935 ("leds: simatic-ipc-leds-gpio: Add GPIO version of Siemens driver")
