[ Upstream commitad6f93e9cd] Clang static analysis reports this representative error init.c:2501:18: warning: Array access (from variable 'queuedata') results in a null pointer dereference templ |= ((queuedata[i] & 0xc0) << 3); This is the problem block of code if(ModeNo > 0x13) { ... if(SiS_Pr->ChipType == SIS_730) { queuedata = &FQBQData730[0]; } else { queuedata = &FQBQData[0]; } } else { } queuedata is not set in the else block Reviewing the old code, the arrays FQBQData730 and FQBQData were used directly. So hoist the setting of queuedata out of the if-else block.

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.
