Subject: [PATCH] nand: mxc: Use appropriate page number in syndrome functions
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
The syndrome functions should use the page number passed as argument instead of
the page number saved upon NAND_CMD_READ0.
This does not make any difference if the NAND_NO_AUTOINCR option is set, but
otherwise this fixes accesses to the wrong pages.
