Use the GFP_ATOMIC flag of kzalloc() with two memory allocation in report_del_sta_event(). This function is called while holding spinlocks, therefore it is not allowed to sleep. With the GFP_ATOMIC type flag, the allocation is high priority and must not sleep. This issue is detected by Smatch which emits the following warning: "drivers/staging/r8188eu/core/rtw_mlme_ext.c:6848 report_del_sta_event() warn: sleeping in atomic context". After the change, the post-commit hook output the following message: "CHECK: Prefer kzalloc(sizeof(*pcmd_obj)...) over kzalloc(sizeof(struct cmd_obj)...)". According to the above "CHECK", use the preferred style in the first kzalloc(). Fixes: |

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.
