Subject: [patch -next] typhoon: memory corruption in typhoon_get_drvinfo()

info->version only has space for 32 characters but my UTS_RELEASE is
"2.6.37-rc6-next-20101217-05817-ge935fc8-dirty" so it doesn't fit.
This is supposed to be the version of the driver, not the kernel
version.  This driver doesn't have a version so lets just leave it
blank.
