SubjectRe: [PATCH v4 3/7] phy: add A3700 COMPHY support
Hello,

I received the following bug report because I added a dependency on
COMPILE_TEST in Kconfig:

config: i386-allmodconfig (attached as .config) compiler:
gcc-7 (Debian 7.3.0-1) 7.3.0 reproduce:
# save the attached .config to linux build tree
make ARCH=i386

All errors (new ones prefixed by >>):

>> ERROR: "__arm_smccc_smc" [drivers/phy/marvell/phy-mvebu-a3700-comphy.ko] undefined!

Unless someone complains, I will drop the dependency on COMPILE_TEST in
Kconfig.

Thanks,
Miquèl
