Description

dpll: fix xa_alloc_cyclic() error handling

In the Linux kernel, the following vulnerability has been resolved:

dpll: fix xa_alloc_cyclic() error handling

In case of returning 1 from xa_alloc_cyclic() (wrapping) ERR_PTR(1) will

be returned, which will cause IS_ERR() to be false. Which can lead to

dereference not allocated pointer (pin).

Fix it by checking if err is lower than zero.

This wasn't found in real usecase, only noticed. Credit to Pierre.
