[PARISC] pdc_console: fix bizarre panic on boot
Commit 721fdf34167580ff98263c74cead8871d76936e6 introduced a subtle bug by accidently removing the "static" from iodc_dbuf. This resulted in, what appeared to be, a trap without *current set to a task. Probably the result of a trap in real mode while calling firmware. Also do other misc clean ups. Since the only input from firmware is non blocking, share iodc_dbuf between input and output, and spinlock the only callers. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
