There is still no fix for the mips:allmodconfig build problem as far
as I can see. It is a bit odd, because the fix would be as simple as
- tristate "MediaTek MT7621 PCIe Controller"
- depends on (RALINK && SOC_MT7621) || (MIPS && COMPILE_TEST)
+ bool "MediaTek MT7621 PCIe Controller"
+ depends on SOC_MT7621 || (MIPS && COMPILE_TEST)
Context: tristate doesn't make sense here because both RALINK and
SOC_MT7621 are bool. Also, RALINK is redundant because SOC_MT7621
already depends on it. The compile failure is due to missing exported
symbols, and it is only seen if PCIE_MT7621=m - which is only possible
if COMPILE_TEST=y. In other words, the dependencies above are set such
that test builds, and only test builds, fail.
The problem was introduced with commit 2bdd5238e756 ("PCI: mt7621:
Add MediaTek MT7621 PCIe host controller driver"). Copying some of
those responsible to see if we can expect a solution sometime soon.
