2026-01-16gpib: Fix memory leak in ni_usb_init()Zilin Guan
In ni_usb_init(), if ni_usb_setup_init() fails, the function returns -EFAULT without freeing the allocated writes buffer, leading to a memory leak. Additionally, ni_usb_setup_init() returns 0 on failure, which causes ni_usb_init() to return -EFAULT, an inappropriate error code for this situation. Fix the leak by freeing writes in the error path. Modify ni_usb_setup_init() to return -EINVAL on failure and propagate this error code in ni_usb_init().

This entails: - Remove the gpib Kconfig menu and Makefile build rule from staging. - Remove gpib/uapi from the header file search path in subdir-ccflags of the gpib Makefile - move the gpib/uapi files to include/uapi/linux - Move the gpib tree out of staging to drivers. - Remove the word "Linux" from the gpib Kconfig file. - Add the gpib Kconfig menu and Makefile build rule to drivers Signed-off-by: Dave Penkler <dpenkler@gmail.com> Link: https://patch.msgid.link/20251117144021.23569-5-dpenkler@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
