[ Upstream commit af1c0e4e00f3cc76cb136ebf2e2c04e8b6446285 ] When a frame with NULL DSAP is received, llc_station_rcv is called. In turn, llc_stat_ev_rx_null_dsap_xid_c is called to check if it is a NULL XID frame. The return statement of llc_stat_ev_rx_null_dsap_xid_c returns 1 when the incoming frame is not a NULL XID frame and 0 otherwise. Hence, a NULL XID response is returned unexpectedly, e.g. when the incoming frame is a NULL TEST command. To fix the error, simply remove the conditional operator. A similar error in llc_stat_ev_rx_null_dsap_test_c is also fixed. Signed-off-by: Chan Shu Tak, Alex <alexchan@task.com.hk> Signed-off-by: David S.

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.
