The 9p code for some reason used to initialize variables outside of the
declaration, e.g. instead of just initializing the variable like this:
int retval = 0
We would be doing this:
int retval;
retval = 0;
This is perfectly fine and the compiler will just optimize dead stores
anyway, but scan-build seems to think this is a problem and there are
many of these warnings making the output of scan-build full of such
warnings:
fs/9p/vfs_inode.c:916:2: warning: Value stored to 'retval' is never read [deadcode.DeadStores]
retval = 0;
^ ~
I have no strong opinion here, but if we want to regularly run
scan-build we should fix these just to silence the messages.
I've confirmed these all are indeed ok to remove.
