Smatch pointed out this trivial typo:
drivers/dma-buf/dma-buf.c:1123 dma_buf_map_attachment()
warn: passing positive error code '16' to 'ERR_PTR'
drivers/dma-buf/dma-buf.c
1113 dma_resv_assert_held(attach->dmabuf->resv);
1114
1115 if (dma_buf_pin_on_map(attach)) {
1116 ret = attach->dmabuf->ops->pin(attach);
1117 /*
1118 * Catch exporters making buffers inaccessible even when
1119 * attachments preventing that exist.
1120 */
1121 WARN_ON_ONCE(ret == EBUSY);
^^^^^
This was probably intended to be -EBUSY?
1122 if (ret)
--> 1123 return ERR_PTR(ret);
^^^
Otherwise we will eventually crash.
1124 }
1125
1126 sg_table = attach->dmabuf->ops->map_dma_buf(attach, direction);
1127 if (!sg_table)
1128 sg_table = ERR_PTR(-ENOMEM);
1129 if (IS_ERR(sg_table))
1130 goto error_unpin;

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
