   4 Subject: [PATCH 124/203] mtd: nand: pxa3xx: Add __maybe_unused keyword to
   5  enable_int()
   6
   7 Now that we have added ARCH_HAS_DMA conditional the function
   8 enable_int() may be unused. Declare it as __maybe_unused,
   9 in order to remove the following warning, when the function is not used:
  10
  11 drivers/mtd/nand//pxa3xx_nand.c:343:24: warning: 'enable_int' defined
  12 but not used [-Wunused-function]
