Subject: net: nps_enet: Fix module autoload
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fc971a2f2383950ddedb1e4896c5ead5d2357029;p=linux-beck.git

net: nps_enet: Fix module autoload

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/net/ethernet/ezchip/nps_enet.ko | grep alias
$

After this patch:

$ modinfo drivers/net/ethernet/ezchip/nps_enet.ko | grep alias
alias:          of:N*T*Cezchip,nps-mgt-enetC*
alias:          of:N*T*Cezchip,nps-mgt-enet
