Subject: [SCSI] qla2xxx: Defer explicit interrupt-polling processing to init-time scenarios.
X-Git-Tag: v2.6.24-rc1~19^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a3a63d55a4eec418d845a91222ac53443f62717b;p=platform%2Fkernel%2Flinux-3.10.git

[SCSI] qla2xxx: Defer explicit interrupt-polling processing to init-time scenarios.

As the intermixing may cause issues where HCCR bits could be
cleared inappropriately during MSI/MSI-X interrupt handling.
