Jiri Slaby (SUSE) 4a2ad26613 tty: n_tty: use 'retval' instead of 'c' 
In n_tty_read(), there is a separate int variable 'c' and is used only
to hold an int value returned from job_control(). There is also a
'retval' variable typed ssize_t. So drop this single occurrence of 'c'
and reuse 'retval' which is used on all other places to hold the value
returned from n_tty_read().

Note that 'retval' needs not be initialized now. Drop that.
