From: James Smart Date: Mon, 7 Jun 2010 19:23:35 +0000 (-0400) Subject: [SCSI] lpfc 8.3.13: Initialization code clean up and fixes. X-Git-Tag: v2.6.36-rc1~570^2~228 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6e7288d9a4b6691bf13fb07e3593d70d725d0737;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git [SCSI] lpfc 8.3.13: Initialization code clean up and fixes. - Add poll or wait flag parameter to hba_init_link and hba_down_link. - (From Linux Community) Make return with ENXIO negative. - Remove unused INB code from driver. - Prevent block_magmt_io from returning until mailbox is inactive.
