Subject: [PATCH 2/2] openrisc: mm/init.c: remove unused variable 'end' in paging_init()

From: Mike Rapoport <rppt@...ux.ibm.com>

A build with W=1 enabled produces the following warning:

  CC      arch/openrisc/mm/init.o
arch/openrisc/mm/init.c: In function 'paging_init':
arch/openrisc/mm/init.c:131:16: warning: variable 'end' set but not used [-Wunused-but-set-variable]
  131 |  unsigned long end;
      |                ^~~

Remove the unused variable 'end'.
