The patch is good, there are few nitpicks however. Would you please fix them?

When running checkpatch I get:
$ ./scripts/checkpatch.pl --strict
V3-mtd-spi-nor-split-s25fl128s-into-s25fl128s0-and-s25fl128s1.patch
WARNING: line over 80 characters

Please choose the following format, it has fewer lines:
        { "s25fl128s0", INFO6(0x012018, 0x4d0080, 256 * 1024, 64,
                        SPI_NOR_DUAL_READ | SPI_NOR_QUAD_READ | USE_CLSR) },
        { "s25fl128s1", INFO6(0x012018, 0x4d0180, 64 * 1024, 256,
                        SPI_NOR_DUAL_READ | SPI_NOR_QUAD_READ | USE_CLSR) },

While here, would you please place these 2 entries in alphabetical order? They
belong just before "s25fl256s0" entry.

Thanks!
