[ALSA] snd-ca0106, snd-emu10k1: Add symlink in the sys tree.
CA0106 driver,EMU10K1/EMU10K2 driver
A thread appeared on the LKML. This patch implements the fix.
Question:
in sysfs, /sys/bus/*/drivers lists the driver names, with their exported .name (eg. '.name = 'EMU10K1_Audigy'' in the module code, from now on 'driver name'). In /sys/modules, the kernel modules are listed with their module name, eg. snd_emu10k1. However, it seems to me that in sysfs, there is no way in particular to tell, which module has which .name. That is, that snd_emu10k1 is EMU10K1_Audigy and vice versa.
I wonder whether it wouldn't be possible to add a symlink to the particular module from the driver, and/or from the module to the driver, so the list of devices handled by the module and the module name would be accessible. This way, I would know which driver name corresponds to which module name and vice versa.
Answer:
For PCI drivers, just add the line:
.owner = THIS_MODULE,
to their struct pci_driver definition and you will get the symlink
created for you.
