drm\/imagination: Fix user array stride in pvr_set_uobj_array()<\/p>\n
pvr_set_uobj_array() copies an array of kernel objects to a userspace
\narray whose element size is described by out->stride. When out->stride
\nis different from the kernel object size, the slow path advances the
\nuserspace pointer by the kernel object size and the kernel pointer by the
\nuserspace stride.<\/p>\n
This reverses the intended layout. For larger userspace strides, later
\ncopies read from the wrong kernel addresses. For smaller userspace
\nstrides, later copies are written at the wrong userspace offsets. The
\npadding clear is also done only for the first element instead of the
\npadding area for each element.<\/p>\n
Advance the userspace pointer by out->stride and the kernel pointer by
\nobj_size, and clear per-element padding while the current userspace
\npointer is still available.<\/p>\n","protected":false},"excerpt":{"rendered":"
