Allocate memory only if we're asked to enqueue the command for later processing. Handle memory allocation failures in one place. There's no need to "goto exit" if we're not doing any cleanup there. kzalloc already set all of pdrvextra_cmd_parm to 0. We don't have to set pdrvextra_cmd_parm->pbuf = NULL manually.

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.
