Input: i8042 - fix leaking of platform device on module removal

2022-11-25T16:42:21+00:00

[ Upstream commit 81cd7e8489278d28794e7b272950c3e00c344e44 ] Avoid resetting the module-wide i8042_platform_device pointer in i8042_probe() or i8042_remove(), so that the device can be properly destroyed by i8042_exit() on module unload.

Input: iforce - invert valid length check when fetching device IDs

2022-11-25T16:42:19+00:00

commit b8ebf250997c5fb253582f42bfe98673801ebebd upstream. syzbot is reporting uninitialized value at iforce_init_device() [1], for commit 6ac0aec6b0a6 ("Input: iforce - allow callers supply data buffer when fetching device IDs") is checking that valid length is shorter than bytes to read. Since iforce_get_id_packet() stores valid length when returning 0, the caller needs to check that valid length is longer than or equals to bytes to read.

Input: xpad - fix wireless 360 controller breaking after suspend

2022-10-15T05:54:41+00:00

commit a17b9841152e7f4621619902b347e2cc39c32996 upstream. Suspending and resuming the system can sometimes cause the out URB to get hung after a reset_resume. This causes LED setting and force feedback to break on resume. To avoid this, just drop the reset_resume callback so the USB core rebinds xpad to the wireless pads on resume if a reset happened. A nice side effect of this change is the LED ring on wireless controllers is now set correctly on system resume.

Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flag

commit 98e01215708b6d416345465c09dce2bd4868c67a upstream. syzbot is reporting hung task at __input_unregister_device() [1], for iforce_close() waiting at wait_event_interruptible() with dev->mutex held is blocking input_disconnect_device() from __input_unregister_device(). It seems that the cause is simply that commit c2b27ef672992a20 ("Input: iforce - wait for command completion when closing the device") forgot to call wake_up() after clear_bit(). Fix this problem by introducing a helper that calls clear_bit() followed by wake_up_all().

Input: bcm5974 - set missing URB_NO_TRANSFER_DMA_MAP urb flag

commit c42e65664390be7c1ef3838cd84956d3a2739d60 upstream. The bcm5974 driver does the allocation and dma mapping of the usb urb data buffer, but driver does not set the URB_NO_TRANSFER_DMA_MAP flag to let usb core know the buffer is already mapped. usb core tries to map the already mapped buffer, causing a warning: "xhci_hcd 0000:00:14.0: rejecting DMA map of vmalloc memory" Fix this by setting the URB_NO_TRANSFER_DMA_MAP, letting usb core know buffer is already mapped by bcm5974 driver Signed-off-by: Mathias Nyman Cc: stable@vger.kernel.org Link: https://bugzilla.kernel.org/show_bug.cgi?id=215890 Link: https://lore.kernel.org/r/20220606113636.588955-1-mathias.nyman@linux.intel.com Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman
