X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=06e23b7470ca7974b0ca8150c5415b55b5ea2a99;p=linux-beck.git [SCSI] qla2xxx: Don't explicitly read mbx registers while processing a system-error. Callers of qla2x00_async_event() already populate the mb[] array upon invocation, doing so via the appropriate mailbox register accessors. The stale codes removed are leftover-bits kept during the FWI2 transition. Though relatively benign, the extra-reads are not valid for FWI2 boards (ISP24xx and above) and peek into the incorrect regions of registers.
