[PATCH] staging: typec: fusb302: Fix module autoload

Show all headers | View raw

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 OF and I2C device ID table entries as module aliases, using the
MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/staging/typec/fusb302/fusb302.ko | grep alias
$

After this patch:

$ modinfo drivers/staging/typec/fusb302/fusb302.ko | grep alias
alias:          of:N*T*Cfcs,fusb302C*
alias:          of:N*T*Cfcs,fusb302
alias:          i2c:typec_fusb302
