Commit 59d8053f1e ("proc: Move non-public
stuff from linux/proc_fs.h to fs/proc/internal.h") broke Apple NuBus
support:
drivers/nubus/proc.c: In function ‘nubus_proc_detach_device’:
drivers/nubus/proc.c:156: error: dereferencing pointer to incomplete type
drivers/nubus/proc.c:158: error: dereferencing pointer to incomplete type
Fortunately nubus_proc_detach_device() is unused, and appears to have never
been used, so just remove it.
