From: Andrew Vasquez Date: Wed, 6 Jul 2005 17:30:05 +0000 (-0700) Subject: [SCSI] qla2xxx: Factor-out ISP specific functions to method-based call tables. X-Git-Tag: v2.6.13-rc4~75^2~24 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=abbd8870b9cb7754a4935826bc9f3c7b029f8b7c;p=linux-2.6 [SCSI] qla2xxx: Factor-out ISP specific functions to method-based call tables. Factor-out ISP specific functions to method-based call tables. In anticipation of ISP24xx/ISP25xx support, factor-out ISP specific functions into a method-based call table.
