Return values for *allocate_private functions as well as calling code in
gpib driver are all over the place. Unify them by returning -errno if
something fails, zero otherwise. Use the returned value as early return
value in case of error. Replace kmalloc/memset pairs to kzalloc.

This is multiple things in the same patch, which is not a good idea.
Each change should just do one logical thing, this should be broken up
into much smaller pieces.

thanks,

Wait, there is no kzalloc change here.  You used the same changelog for
all of these patches :(
