NAME

       read_zsreg - Read a register from a Z85230

SYNOPSIS

       u8 read_zsreg  (struct z8530_channel * c, u8 reg);

ARGUMENTS

       c      Z8530 channel to read from (2 per chip)

       reg    Register to read

FIXME

       Use a spinlock.

       Most  of  the  Z8530 registers are indexed off the control registers. A
       read is done by  writing  to  the  control  register  and  reading  the
       register back. The caller must hold the lock
