[PATCH] mtd: aspeed: fix compile warning in aspeed_smc_read_from_ahb()

[Cédric Le Goater]

The first argument of ioread32_rep() and ioread8_rep is not
const. Change aspeed_smc_read_from_ahb() prototype to fix compile
warning :

   drivers/mtd/spi-nor/aspeed-smc.c: In function 'aspeed_smc_read_from_ahb':
   drivers/mtd/spi-nor/aspeed-smc.c:212:16: warning: passing argument 1 of 'ioread32_rep' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
      ioread32_rep(src, buf, len >> 2);
