staging: android: ion: Clean unused debug_show memeber of the heap object
ION had supported heap debug info under /sys/kernel/debug/ion/<heap_name>. This support have been removed but some leftovers (dead code) still exist. This patch removes the existing dead code. Fixes: 15c6098cfec5 ("staging: android: ion: Remove ion_handle and ion_client") Signed-off-by: Alexey Skidanov <alexey.skidanov@intel.com> Acked-by: Laura Abbott <labbott@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
