Subject: [SUNSAB]: Fix several bugs.
X-Git-Tag: v2.6.23-rc7~6^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9c5b34806c28195e4d0f2deaa41d8158ca5874e1;p=pandora-kernel.git

[SUNSAB]: Fix several bugs.

	* don't register irq until ->startup() (and release in ->shutdown()).
That avoids oopsen with the current tree when interrupt comes before we'd
set up the data structures for ttyb.
	* handle console=ttyS... even when OBP talks to screen/keyboard
	* register irq handler for each port, let kernel/irq/handle.c
call it for both if needed.  Kills code duplication in sunsab_interrupt().
BTW, there'd been bitrot in it - ttya handling had stopped calling
check_status() on BRK (correctly), ttyb copy of that code had kept the
bogus call in that case.
