Input: edt-ft5x06 - fix use-after-free in debugfs teardown

2026-04-20T00:54:06+00:00

The commit 68743c500c6e ("Input: edt-ft5x06 - use per-client debugfs directory") removed the manual debugfs teardown, relying on the I2C core to handle it. However, this creates a window where debugfs files are still accessible after edt_ft5x06_ts_teardown_debugfs() frees tsdata->raw_buffer. To prevent a use-after-free, protect the freeing of raw_buffer with the device mutex and set raw_buffer to NULL. The debugfs read function already checks if raw_buffer is NULL under the same mutex, so this safely avoids the use-after-free.

Input: mk712 - remove driver

2026-04-08T14:55:25+00:00

This touchscreen controller was used om Gateway AOL Connected Touchpad released in 2000 and, according to Wikipedia, removed from the market in October 2001 due to slow sales. It looks like it can still be bought on eBay for $1000 but I really doubt anyone will actually use it. Remove the driver.

Input: usbtouchscreen - refactor endpoint lookup

2026-04-01T17:37:38+00:00

Use the common USB helpers for looking up bulk and interrupt endpoints (and determining endpoint numbers) instead of open coding. Note that the NEXIO data interface has two bulk endpoints (see commit 5197424cdccc ("Input: usbtouchscreen - add NEXIO (or iNexio) support") for the descriptors). The lookup in probe handles both bulk-in and interrupt-in endpoints and was added to handle NEXIO devices. Replace the open coded lookup with a lookup for the common interrupt endpoint and an explicit fallback accepting a bulk endpoint. This iterates over the (two) endpoints twice for NEXIO devices but makes it more clear what is going on.

Input: goodix-berlin - report a resolution of 10 units/mm

2026-03-25T16:08:17+00:00

Without a reported resolution, userspace was assuming 1 unit/mm which is wildly wrong: a regular smartphone is clearly not 2.4 meters tall. Most applications do not care much for this kind of raw mm value, but Phosh's on-screen keyboard would accidentally trigger swipe-to-close gestures due to misinterpreting small movements as huge ones. Do what the older goodix.c driver does and set the resolution to 10 units/mm to make sure the numbers calculated by userspace are reasonable.

Input: sx8654 - use IRQF_NOAUTOEN when requesting interrupt

2026-03-25T14:53:59+00:00

Instead of requesting interrupt normally and immediately disabling it with call to disable_irq() use IRQF_NOAUTOEN to keep it disabled until it is needed. This avoids a tiny window when interrupt is enabled but not needed. Signed-off-by: Dmitry Torokhov
