Subject: driver core: Cast to (void *) with __force for __percpu pointer
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d7aa44f5a1f86cb40659eef06035d8d92604b9d5;p=linux.git

driver core: Cast to (void *) with __force for __percpu pointer

Sparse is not happy:

  drivers/base/devres.c:1230:9: warning: cast removes address space '__percpu' of expression

Use __force attribute to make it happy.
