Subject: [net-next:master 238/243] drivers/net/phy/mdio-thunder.c:40:8:
error: implicit declaration of function 'pcim_enable_device'; did you mean
'pci_enable_device'?
Hi Alexander,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git master
head: ccdb51717ba3bdc9585998e4ffd41d70c04dedea
commit: 7e2bc7fb65d544bb8598a0ab64e40ee9c60ded6e [238/243] net: cavium: Drop dependency of NET_VENDOR_CAVIUM on PCI
config: um-allmodconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-16) 7.3.0
reproduce:
git checkout 7e2bc7fb65d544bb8598a0ab64e40ee9c60ded6e
# save the attached .config to linux build tree
make ARCH=um
