This driver has two includes which are in
"arch/mips/include/asm/mach-ralink" and are directly included in the
driver:
* mt7621.h
* ralink_regs.h

This is because this path is directly included in
arch/mips/ralink/Platform for "ralink":

#
# Ralink SoC common stuff
#
cflags-$(CONFIG_RALINK)     += -I$(srctree)/arch/mips/include/asm/mach-ralink

and this driver directly depends on RALINK or COMPILE_TEST (which
might be the problem here):


and this driver directly depends
on RALINK or COMPILE_TEST:

config PHY_MT7621_PCI
    tristate "MediaTek MT7621 PCI PHY Driver"
    depends on (RALINK || COMPILE_TEST) && OF
    select GENERIC_PHY
    select REGMAP_MMIO
    help
      Say 'Y' here to add support for MediaTek MT7621 PCI PHY driver

What is the correct way of fixing this? Include complete path for both
of them like this?

index db79088d5362..cebd53f5a797 100644
--- a/drivers/phy/ralink/phy-mt7621-pci.c

Vinod, please let me know if you want me to send anything for fixing this.
