The return code from uverbs_zalloc() was wrongly checked, it is ERR_PTR
not NULL like other allocators:
drivers/infiniband/hw/mlx5/devx.c:2110 devx_umem_reg_cmd_alloc() warn: passing zero to 'PTR_ERR'
Fixes: 878f7b31c3 ("RDMA/mlx5: Use ib_umem_find_best_pgsz() for devx")

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 Restructured Text 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.
