Question on compiler warning

In his regular article entitled Build regressions/improvements in v3.13-rc6" (, Geert Uytterhoeven reports the following warning regression:

+ /scratch/kisskb/src/drivers/net/wireless/b43/phy_n.c: warning: 'val_addr' may be used uninitialized in this function [-Wuninitialized]: => 178:21

This warning does not show up on any of my compilers, and it should not as the initialization and usage of that variable both take place in conditional branches that are testing exactly the same pointer.

Despite the fact that the warning is bogus, should a patch be submitted to clear it? I lean toward "no" as an answer because that would mask the warning if there were some future change that screwed up the flow; however, I wanted to check with the community.
