linux-next: build warning after merge of the mfd tree

[Stephen Rothwell]

Hi all,

After merging the mfd tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

WARNING: unmet direct dependencies detected for MFD_AT91_USART
  Depends on [n]: HAS_IOMEM [=y] && (ARCH_MICROCHIP || COMPILE_TEST [=n])
  Selected by [y]:
  - SERIAL_ATMEL [=y] && TTY [=y] && HAS_IOMEM [=y] && COMMON_CLK [=y] && (ARCH_AT91 [=y] || ARCH_LAN969X || COMPILE_TEST [=n])

Probably introduced by commit

  ef37a1e24857 ("mfd: at91-usart: Make it selectable for ARCH_MICROCHIP")
