Subject: [SCSI] qla2xxx: Consolidate RISC-parity enablement codes.
X-Git-Tag: v2.6.25-rc1~285^2~23
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3db0652ef986f3bc3d779c4f986330ee3fdd50cc;p=karo-tx-linux.git

[SCSI] qla2xxx: Consolidate RISC-parity enablement codes.

Collapse duplicate codes called during probe() and RISC-reset
into qla2x00_setup_chip().
