Boris Brezillon 4c7e95b1b3 mtd: nand: gpmi: Fix subpage reads ... Commit 25f815f66a ("mtd: nand: force drivers to explicitly send READ/PROG commands") added a call to nand_read_page_op() in gpmi_ecc_read_page(), which means this function now sends a READ0 command and place the data pointer at the beginning of the page. This logic is breaking gpmi_ecc_read_subpage() which was calling gpmi_ecc_read_page() and expected it to only retrieve the data without sending the READ0 command. Create a gpmi_ecc_read_page_data() helper which only does the data retrieval and ECC correction steps and implement gpmi_ecc_read_page() as a wrapper that calls nand_read_page_op()+gpmi_ecc_read_page_data(). This way, gpmi_ecc_read_subpage() can call gpmi_ecc_read_page_data() which restores the logic we had before commit 25f815f66a ("mtd: nand: force drivers to explicitly send READ/PROG commands").
