[BUG bisect] Missing Micrel driver on VF50 (net: phy: check return code when requesting PHY driver module)

[Krzysztof Kozlowski <krzk@kernel.org>]

[-- Attachment #1: Type: text/plain, Size: 1131 bytes --]

Hi,

On today's next (next-20190118) my Colibri VF50 board fails to boot up
from network (DHCP, NFSv4 root). Looks like missing network adapter.
Expected:
[ 3.041773] Micrel KSZ8041 400d1000.ethernet-1:00: attached PHY driver
[Micrel KSZ8041] (mii_bus:phy_addr=400d1000.ethernet-1:00, irq=POLL)

Result:
[ 15.614964] Root-NFS: no NFS server address
[ 15.619353] VFS: Unable to mount root fs via NFS, trying floppy.
[ 15.626762] VFS: Cannot open root device "nfs" or unknown-block(2,0): error -6
[ 15.634252] Please append a correct "root=" boot option; here are the
available partitions:
[ 15.642791] 0100 16384 ram0
[ 15.642804] (driver?)
[ 15.649076] Kernel panic - not syncing: VFS: Unable to mount root fs
on unknown-block(2,0)
[ 15.657423] ---[ end Kernel panic - not syncing: VFS: Unable to mount
root fs on unknown-block(2,0) ]---

Bisect pointed to:
    net: phy: check return code when requesting PHY driver module

Full log and defconfig attached.

Board:
  - Toradex Colibri VF50 on Iris board
    ARMv7, UP, Cortext-A5, NXP VF500, 128 MB RAM, 128 MB NAND
    Systemd: v232
    DHCP, NFSv4 root

Best regards,
Krzysztof
