driver core: Add "*" wildcard support to driver_async_probe cmdline param
There's currently no way to use driver_async_probe kernel cmdline param
to enable default async probe for all drivers. So, add support for "*"
to match with all driver names. When "*" is used, all other drivers
listed in driver_async_probe are drivers that will NOT match the "*".
For example:
* driver_async_probe=drvA,drvB,drvC
drvA, drvB and drvC do asynchronous probing.
* driver_async_probe=*
All drivers do asynchronous probing except those that have set
PROBE_FORCE_SYNCHRONOUS flag.
* driver_async_probe=*,drvA,drvB,drvC
All drivers do asynchronous probing except drvA, drvB, drvC and those
that have set PROBE_FORCE_SYNCHRONOUS flag.
