Staging: ion: fix code style warning from NULL comparisons

This patch replaces several instances where a pointer is compared to NULL
(i.e., `ptr == NULL`) with `!ptr`, which is preferred.

staging: android: ion: Avoid calling free_duped_table() twice

2017-05-18T13:59:38+00:00

Currently, the duplicated sg table is freed in the detach() and
the error path of map_dma_buf() ion's dma_buf_ops.

If a call to dma_buf_map_attachment() fails, the importer is
expected to call dma_buf_detach() to remove the attachment. This
will result in us trying to free the duped sg table twice.

Don't call free_duped_table() in ion_map_dma_buf() to avoid this.
