[ Upstream commit3a9910d7b6] qla2x00_tmf_sp_done() now deletes the timer that will run qla2x00_tmf_iocb_timeout(), but doesn't check whether the timer already expired. Check the return value from del_timer() to avoid calling complete() a second time. Fixes:4440e46d5d("[SCSI] qla2xxx: Add IOCB Abort command asynchronous ...") Fixes:1514839b36("scsi: qla2xxx: Fix NULL pointer crash due to active ...")

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.
