Subject: V4L/DVB (4275): The FE_SET_FRONTEND_TUNE_MODE ioctl always returns EOPNOTSUPP
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1b172e0c4e44151cd239c1e9260c7822a4eecdbf;p=linux-beck.git

V4L/DVB (4275): The FE_SET_FRONTEND_TUNE_MODE ioctl always returns EOPNOTSUPP

When someone added the front-end ioctl FE_SET_FRONTEND_TUNE_MODE, they
forgot to set the return value to 0.  It always returns EOPNOTSUPP,
causing problems for programmers who actually check for error conditions.
