This introduces a warning:
-----8<-----
  In file included from /builds/linux/block/genhd.c:28:
  /builds/linux/block/genhd.c: In function 'disk_release':
  /builds/linux/include/linux/blktrace_api.h:88:33: warning: statement
with no effect [-Wunused-value]
   # define blk_trace_remove(q)    (-ENOTTY)
                                   ^
  /builds/linux/block/genhd.c:1187:2: note: in expansion of macro
'blk_trace_remove'
    blk_trace_remove(disk->queue);
    ^~~~~~~~~~~~~~~~
----->8-----

This is again with Arm 32-bits on omap1_defconfig.

Bisection points to "block: fix blktrace debugfs entries leakage"
(d8c9d0067dbd here, dd7de3704af9 upstream). Reverting this commit
makes the warning go away.
