linux-next: build failure after merge of the phy-next tree

[broonie]

Hi all,

After merging the phy-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

/tmp/next/build/drivers/phy/freescale/phy-fsl-imx8m-pcie.c: In function 'imx8_pcie_phy_init':
/tmp/next/build/drivers/phy/freescale/phy-fsl-imx8m-pcie.c:41:37: error: implicit declaration of function 'FIELD_PREP' [-Werror=implicit-function-declaration]

I have used the phy-next tree from yesterday.
