Subject: [PATCH 0/5] Input: replace strlcat() with strscpy() in USB input drivers
Date: Sat, 17 Oct 2026 01:04:06 +0800 [thread overview]
Message-ID: <20261016170411.51025-1-shlomojune6@gmail.com> (raw)
Several USB input drivers build the physical path by appending a
constant "/input0" suffix with strlcat() after usb_make_path().
In preparation for removing the deprecated strlcat() API [1],
replace it with strnlen() followed by strscpy() into the remainder
of the buffer, as commit 34b228b739f5 ("HID: usbhid: replace
strlcat with better alternatives") did for the usbhid drivers.
The series is split by input subdirectory:
1/5: joystick drivers (pxrc, xpad)
2/5: misc drivers (ati_remote2, cm109, ims-pcu, keyspan_remote,
powermate, yealink)
3/5: mouse drivers (appletouch, bcm5974, synaptics_usb)
4/5: tablet drivers (acecad, aiptek, hanwang, kbtab,
pegasus_notetaker)
5/5: touchscreen drivers (sur40, usbtouchscreen)
