3.16.39-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Vincent Stehlé <vincent.stehle@xxxxxxxxx>
commit c0082e985fdf77b02fc9e0dac3b58504dcf11b7a upstream.
An assertion in layout_in_gaps() verifies that the gap_lebs pointer is
below the maximum bound. When computing this maximum bound the idx_lebs
count is multiplied by sizeof(int), while C pointers arithmetic does take
into account the size of the pointed elements implicitly already. Remove
the multiplication to fix the assertion.
Fixes: 1e51764a3c2ac05a ("UBIFS: add new flash file system")
