[1/2] media: mei_csi: Fix driver modalias not matching device modalias
Commit Message
The name field of struct mei_cl_device_id is only intended for use
with NFC devices where different devices share the same GUID,
see drivers/misc/mei/bus-fixup.c which sets the name field to
"microread" or "pn544".
For all other mei devices the name field is unset and specifying
it in the drivers mei_cl_device_id MODULE_DEVICE_TABLE() leads
to the driver not properly being autoloaded by modprobe since
it causes the module's alias to not match:
cat .../spi-INTC1094:00-92335fcf-3203-4472-af93-7b4453ac29da/modalias
mei::92335fcf-3203-4472-af93-7b4453ac29da:01:
modinfo mei_csi | grep alias
mei:vsc_csi:92335fcf-3203-4472-af93-7b4453ac29da:*:*
Things still work when manually loading the module because
mei_cl_device_find() only matches the name when the *device* has a name
set, so setting it in the id_table of the driver does not matter.
Drop setting the name in mei_csi_tbl[] so that modprobe will
properly autoload the module.
This makes the mei_cl_device_id use identical to all
the other non NFC mei drivers:
drivers/misc/mei/gsc_proxy/mei_gsc_proxy.c
drivers/misc/mei/hdcp/mei_hdcp.c
drivers/misc/mei/pxp/mei_pxp.c
drivers/watchdog/mei_wdt.c
