       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
