vc_decode_insn() calls copy_from_kernel_nofault() by way of vc_fetch_insn_kernel() to fetch 15 bytes max of opcodes to decode. copy_from_kernel_nofault() returns negative on error and 0 on success. The error case is handled by returning ES_EXCEPTION. In the success case, the ret variable which contains the return value is 0 so there's no need to subtract it from MAX_INSN_SIZE when initializing the insn buffer for further decoding. Remove it. No functional changes. Signed-off-by: Borislav Petkov <bp@suse.de> Reviewed-by: Joerg Roedel <jroedel@suse.de> Link: https://lkml.kernel.org/r/20210223111130.16201-1-bp@alien8.de |

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.
