When the device is instantiated through the OF code path the compatible will be matched against the MODULE_DEVICE_TABLE(of, ) and if the device is programmatically registered (through platform_device_register_*()) then the alias "platform:XYZ" will be used. So, unless we're going to support module autoloading of this driver from a board file no alias should be needed.

Nope we dont, so will drop this one and as well as from SM8150 driver -- ~Vinod

MODULE_ALIAS was missing for this driver which can be built as a module, so add the MODULE_ALIAS. Signed-off-by: Vinod Koul <vkoul@kernel.org> --- drivers/clk/qcom/gcc-qcs404.c | 1 + 1 file changed, 1 insertion(+) -- 2.20.1
