Looking at the handling of service instance within the VCHIQ driver shows that it's not possible that service_callback is called with instance is a NULL pointer. So drop the unnecessary NULL check and fix: vchiq_arm.c:1109 service_callback() warn: variable dereferenced before check 'instance' (see line 1091) Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/linux-arm-kernel/202404230315.vx7ESZ3r-lkp@intel.com/ Signed-off-by: Stefan Wahren <wahrenst@gmx.net> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com> Link: https://lore.kernel.org/r/20240425165852.6681-2-wahrenst@gmx.net Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
