Input: Switch i2c drivers back to use .probe()2023-05-17T16:59:11+00:00Uwe Kleine-Königu.kleine-koenig@pengutronix.de2023-05-17T16:55:42+00:00urn:sha1:d8bde56dfd86a0bba9206de8574e58c8aaac4f0f
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

We need to stop the timer on driver unbind or probe failures, otherwise
we get UAF/Oops.

Input: exc3000 - fix return value check of wait_for_completion_timeout2022-06-29T05:45:43+00:00Miaoqian Linlinmq006@gmail.com2022-06-29T05:42:35+00:00urn:sha1:6bb7144c3fa16a5efb54a8e2aff1817b4168018e
wait_for_completion_timeout() returns unsigned long not int.
It returns 0 if timed out, and positive if completed.
The check for <= 0 is ambiguous and should be == 0 here
indicating timeout which is the only error case.

Input: exc3000 - fix firmware version query for device in bootloader2021-03-08T05:56:49+00:00Lucas Stachl.stach@pengutronix.de2021-03-08T05:40:01+00:00urn:sha1:c929ac9eb85acf9217eb812369bbd4cf65a772e0
If the device is stuck in bootloader (maybe due to blank or corrupted
application firmware) it won't answer a query for the firmware version.
Fall back to returning the bootloader version in that case.

Factor out the vendor data i2c request handling to make it reusable
for other functions. Also don't cache the model and firmware version
string in the device private data as we never use the cached version,
but always read from the device.

Input: exc3000 - split MT event handling from IRQ handler2021-03-08T05:56:46+00:00Lucas Stachl.stach@pengutronix.de2021-03-08T05:10:57+00:00urn:sha1:a63d0120a2dd89eabf24b415b27208e190e989b0
Split out the multitouch event handling into its own function to allow other
events to be handled in the IRQ handler without disturbing the MT handling.
Now that things are separated a bit more, stop treating vendor data requests
special by cehcking for a locked mutex, but just look at the event ID to
figure out if the message is a MT report or a vendor data query reply.
