If you're editing a .h file then you need to compile all the stuff which
includes it.  It's slightly complicated.  But if you're just editing a
.c file like here then what I do is I have use my Smatch script to try
compile it.

In Debian run:
apt-get install gcc make sqlite3 libsqlite3-dev libdbd-sqlite3-perl libssl-dev libtry-tiny-perl
Or in Fedora run:
yum install gcc make sqlite3 sqlite-devel sqlite perl-DBD-SQLite openssl-devel perl-Try-Tiny

git clone https://github.com/error27/smatch.git
cd smatch
make

cd /path/to/kernel_src/
~/smatch/smatch_scripts/kchecker drivers/staging/nvec/nvec_paz00.c

Also I run Sparse on the file.
~/smatch/smatch_scripts/kchecker --sparse drivers/staging/nvec/nvec_paz00.c

When I'm patching a file, then I like to look at any other issues I
might want to fix and deal with that as well.
