Subject: mtd: rawnand: constify elements of NAND_OP_PARSER(_PATTERN)
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f56cad5fd6cd876d0cab9d13d9df7bebf6fddf59;p=openwrt%2Fstaging%2Fblogic.git

mtd: rawnand: constify elements of NAND_OP_PARSER(_PATTERN)

Currently, drivers are able to constify a nand_op_parser array,
but not nand_op_parser_pattern and nand_op_parser_pattern_elem
since they are instantiated by using the NAND_OP_PARSER(_PATTERN).

Add 'const' to them in order to move more driver data from .data to
.rodata section.
