X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fd00f7c1034391efa55bf87235a933fd76975af9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [SCSI] pm8001: fix endian issue with code optimization. Data type of the 'tag' field of 'fw_flash_Update_resp' should be __le32. Data type of 'pHeader' should be __le32. Remove 2nd cast to 'piomb'.
