I get some static checker warnings like this:
drivers/staging/rts5208/ms.c:2607 ms_build_l2p_tbl()
error: buffer underflow 'ms_card->segment' (-1)-16
The problem is that we memset "ms_card" to zero at the start of the
reset_ms_card() function. That means that when we try to calculate
"ms_card->total_block / 512 - 1" then it's just always -1. The fix is
to calculate "seg_no" before doing the memset().
This is a static checker fix, and I am not able to test it. My theory
is that reset_ms_card() gets very little testing which is why this bug
exists.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
