Input: Fix memory leak in psxpad_spi_probe

2019-12-13T07:42:44Z

In the implementation of psxpad_spi_probe() the allocated memory for pdev is leaked if psxpad_spi_init_ff() or input_register_polled_device() fail. The solution is using device managed allocation, like the one used for pad. Perform the allocation using devm_input_allocate_polled_device().

Input: goodix - add upside-down quirk for Teclast X89 tablet

2019-12-13T07:42:42Z

commit df5b5e555b356662a5e4a23c6774fdfce8547d54 upstream. The touchscreen on the Teclast X89 is mounted upside down in relation to the display orientation (the touchscreen itself is mounted upright, but the display is mounted upside-down). Add a quirk for this so that we send coordinates which match the display orientation.

Input: synaptics-rmi4 - don't increment rmiaddr for SMBus transfers

2019-12-13T07:42:42Z

commit a284e11c371e446371675668d8c8120a27227339 upstream. This increment of rmi_smbus in rmi_smb_read/write_block() causes garbage to be read/written. The first read of SMB_MAX_COUNT bytes is fine, but after that it is nonsense. Trial-and-error showed that by dropping the increment of rmiaddr everything is fine and the F54 function properly works. I tried a hack with rmi_smb_write_block() as well (writing to the same F54 touchpad data area, then reading it back), and that suggests that there too the rmiaddr increment has to be dropped. It makes sense that if it has to be dropped for read, then it has to be dropped for write as well. It looks like the initial work with F54 was done using i2c, not smbus, and it seems nobody ever tested F54 with smbus. The other functions all read/write less than SMB_MAX_COUNT as far as I can tell, so this issue was never noticed with non-F54 functions. With this change I can read out the touchpad data correctly on my Lenovo X1 Carbon 6th Gen laptop.

Input: synaptics-rmi4 - re-enable IRQs in f34v7_do_reflash

2019-12-13T07:42:41Z

commit 86bcd3a12999447faad60ec59c2d64d18d8e61ac upstream. F34 is a bit special as it reinitializes the device and related driver structs during the firmware update. This clears the fn_irq_mask which will then prevent F34 from receiving further interrupts, leading to timeouts during the firmware update. Make sure to reinitialize the IRQ enables at the appropriate times. The issue is in F34 code, but the commit in the fixes tag exposed the issue, as before this commit things would work by accident.

This reverts commit 68b9c5066e39af41d3448abfc887c77ce22dd64d. Ugh, I really dropped the ball on this one :\. So as it turns out RMI4 works perfectly fine on the X1 Extreme Gen 2 except for one thing I didn't notice because I usually use the trackpoint: clicking with the touchpad. Somehow this is broken, in fact we don't even seem to indicate BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even see any RMI4 events coming from the touchpad when I press down on it. This only seems to work for PS/2 mode. Since that means we have a regression, and PS/2 mode seems to work fine for the time being - revert this for now. We'll have to do a more thorough investigation on this.

Input: synaptics-rmi4 - destroy F54 poller workqueue when removing

2019-11-15T19:46:33Z

The driver forgets to destroy workqueue in remove() similarly to what is done when probe() fails. Add a call to destroy_workqueue() to fix it. Since unregistration will wait for the work to finish, we do not need to cancel/flush the work instance in remove().
