[REGRESSION] stmmac_platform: Unknown symbol devm_kmalloc (err 0)

[REGRESSION] stmmac_platform: Unknown symbol devm_kmalloc (err 0)

[Igor Gnatenko]

Hi all, stmmac driver doesn't work on cubietruck (and some more
devices like PcDuino3 Nano[0]).

This error comes from converting dwmac-sunxi to platform driver.

stmmac_platform: module license 'unspecified' taints kernel.
Disabling lock debugging due to kernel taint
stmmac_platform: Unknown symbol devm_kmalloc (err 0)
stmmac_platform: Unknown symbol stmmac_suspend (err 0)

stmmac_platform: Unknown symbol of_alias_get_id (err 0)
stmmac_platform: Unknown symbol stmmac_resume (err 0)
stmmac_platform: Unknown symbol stmmac_dvr_probe (err 0)

I've filled bugreport with the same info[1]. What info I would provide
to help with fixing this?

Ah, I guess 50649ab14982a ("stmmac: drop driver from stmmac platform
code") was a over eager when removing stuff. I should have kept the
MODULE_* macro's as stmmac_platform can still be a module. I'll send
out a patch a bit later with a CC to you.

I'll look into this as well.

Thanks for reporting. If you could test patch I will send out soon
that would be of great help.

[PATCH net] stmmac: fix missing MODULE_LICENSE in stmmac_platform

[Joachim Eastwood]

Commit 50649ab14982 ("stmmac: drop driver from stmmac platform code")
was a bit overzealous in removing code and dropped the MODULE_*
macro's that are still needed since stmmac_platform can be a module.
Fix this by putting the macro's remvoed in 50649ab14982 back.

This fixes the following errors when used as a module:
  stmmac_platform: module license 'unspecified' taints kernel.
  Disabling lock debugging due to kernel taint
  stmmac_platform: Unknown symbol devm_kmalloc (err 0)
  stmmac_platform: Unknown symbol stmmac_suspend (err 0)
  stmmac_platform: Unknown symbol platform_get_irq_byname (err 0)
  stmmac_platform: Unknown symbol stmmac_dvr_remove (err 0)
  stmmac_platform: Unknown symbol platform_get_resource (err 0)
  stmmac_platform: Unknown symbol of_get_phy_mode (err 0)
  stmmac_platform: Unknown symbol of_property_read_u32_array (err 0)
  stmmac_platform: Unknown symbol of_alias_get_id (err 0)
  stmmac_platform: Unknown symbol stmmac_resume (err 0)
  stmmac_platform: Unknown symbol stmmac_dvr_probe (err 0)

Hi,

An alternative solution could be to change CONFIG_STMMAC_PLATFORM
into a bool, but I guess we want to keep things as modular as
possible.

Please test this Igor and report back. Thanks!

Hi,

Sorry for the resend, I managed to screwed up Igor's email address
in the previous one.

I've just get's home. It works, thanks for quick fix!

I think also lacks of reference tag.
