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/qualcomm/emac/qcom-emac.ko | grep alias
alias: platform:qcom-emac
After this patch:
$ modinfo drivers/net/ethernet/qualcomm/emac/qcom-emac.ko | grep alias

Add support for reading addresses, interrupts, and _DSD properties
from ACPI tables, just like with device tree. The HID for the
EMAC device itself is QCOM8070. The internal PHY is represented
by a child node with a HID of QCOM8071.
The EMAC also has some complex clock initialization requirements
that are not represented by this patch. This will be addressed
in a future patch.

Replace the DT-specific of_get_mac_address() function with
device_get_mac_address, which works on both DT and ACPI platforms. This
change makes it easier to add ACPI support.

The platform_device returned by of_find_device_by_node() is not
automatically released when the driver unprobes. Therefore,
managed calls like devm_ioremap_resource() should not be used.
Instead, we manually allocate the resources and then free them
on driver release.

Remove .owner field if calls are used which set it automatically.

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

Add support for the Qualcomm Technologies, Inc. EMAC gigabit Ethernet
controller.
This driver supports the following features:
1) Checksum offload.
2) Interrupt coalescing support.
3) SGMII phy.
4) phylib interface for external phy
