John Baldwin 84f9a0e5c5 Fix lptopen() and lptclose() to not trash the state of the HAVEBUS flag ... in 'sc_state'. This allows the lpt_release_ppbus() calls in those two routines to actually release the ppbus and thus fixes the hangs noticed with the lpt(4) driver since the recent ppbus changes. The old lpt(4) driver didn't actually check the HAVEBUS flag in lpt_release_ppbus() which is why these bugs weren't noticed before.		2009-02-11 14:25:09 +00:00
