chip driver mar_ram.c never sets MTD_ERASE_DONE state

["Oliver Kühlert" <oliver.kuehlert@sysgo.com>]

Hello,

trying to erase on an mtd devices using the map_ram.c driver
blocks the current process and never wakes up. (see mtdchar.c, ioctl func)

I believe, that this can be fixed by adding the marked line in map_ram.c:


static int mapram_erase (struct mtd_info *mtd, struct erase_info *instr)
{
         /* Yeah, it's inefficient. Who cares? It's faster than a _real_
            flash erase. */
         struct map_info *map = (struct map_info *)mtd->priv;
         unsigned long i;

         for (i=0; i<instr->len; i++)
                 map_write8(map, 0xFF, instr->addr + i);

!!!!!!---->   instr->state = MTD_ERASE_DONE;   <----- !!!!!!

         if (instr->callback)
                 instr->callback(instr);

         return 0;
}

Best regards, Oliver Kühlert
