Re: [PATCH] [SCSI] pm8001: fix endian issue with code optimization.

[Mark Salyzyn]

NAK on one point.

The fw_flash_Update_resp structure erroneously defines tag as a dma_addr_t, when in fact it should be an __le32, as the response hTag is reported in this field. The removal of the le32_to_cpu(ppayload->tag) was done to remove a warning, but is incorrect. The warning should have been solved by correctly defining the tag element in the structure.
