In this patch series are fixes for issues I found during recent tests of an MCP2221 board. - you can confuse the kernel driver when using the chip from user mode via /dev/hidrawX, typically leading to a NULL pointer dereference in the driver's HID raw event handler - the driver needs > 15s to initialize because the HID raw handling is not enabled during initialization of the GPIO part - the rxbuf pointer can become invalid or even stale if the device would send unsolicited reports Changes in v2: - removed: data shared with the bottom half code is not protected from concurrent access Feedback if this is actually needed or not would be appreciated. - rebased on linux-hid/for-6.2/mcp2221 Enrik Berkhan (3): HID: mcp2221: don't connect hidraw HID: mcp2221: enable HID I/O during GPIO probe HID: mcp2221: avoid stale rxbuf pointer drivers/hid/hid-mcp2221.c | 51 +++++++++++++++++++++++++++++++-------- 1 file changed, 41 insertions(+), 10 deletions(-) base-commit: 3d74c9eca1a2bda03e45f18d13154ac3e0dfba85 -- 2.34.1
