SubjectRe: [PATCH] next: input: Fix build error seen if input-core is built as module
Hello,

I have already submitted a patch to fix it, here it is again:



Now that input/leds.c is compiled into the input.ko module in the mm
tree, its init and exit function must be called by input.ko's init and
exit functions, instead of duplicating the module init/exit hooks, which
leads to the following build error when input is built as a module:

leds.c:(.init.text+0x0): multiple definition of `init_module'
leds.c:(.exit.text+0x0): multiple definition of `cleanup_module'

This also adds a proper clean of the vt_led_work queues in the exit
function.

This is a follow-up to the following reports:

Re: [next:master 9776/10302] leds.c:(.init.text+0x0): multiple definition of `init_module'
Re: [next:master 9391/10970] leds.c:(.exit.text+0x0): multiple definition of `cleanup_module'

and to be applied over the existing
input-route-kbd-leds-through-the-generic-leds-layer-fix-2
please.

Thanks!
Samuel
