Description

In the Linux kernel, the following vulnerability has been resolved: gpio: cdev: Avoid NULL dereference in linehandle_create() In linehandle_create(), there is a statement like this: retain_and_null_ptr(lh); Soon after, there is a debug printout that dereferences "lh", which will crash things. Avoid the crash by using handlereq.lines, which is the same value.
