    kernel: fix compiler warning in mtdsplit_minor.c under 4.4
    
    When mtdsplit_minor.c is compiled under Linux 4.4, the compiler
    drops the following warning:
    
        CC      drivers/mtd/mtdsplit/mtdsplit_minor.o
      drivers/mtd/mtdsplit/mtdsplit_minor.c:106:14: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
        .parse_fn = mtdsplit_parse_minor,
                    ^
      drivers/mtd/mtdsplit/mtdsplit_minor.c:106:14: note: (near initialization for 'mtdsplit_minor_parser.parse_fn')
    
    The second parameter of the parser function must not have a 'const'
    qualifier in 4.4. The 001-mtdsplit_backport.patch removes the qualifier
    from other partition parsers. Update it to handle mtdsplit_minor.c as
    well.
