[ Upstream commit7525858679] In digital_tg_recv_dep_req, it calls nfc_tm_data_received(..,resp). If nfc_tm_data_received() failed, the callee will free the resp via kfree_skb() and return error. But in the exit branch, the resp will be freed again. My patch sets resp to NULL if nfc_tm_data_received() failed, to avoid the double free.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
