[PATCH] [RESEND^2] media: don't drop front-end reference count for ->detach

by Arnd Bergmann

A bugfix introduce a link failure in configurations without CONFIG_MODULES: In file included from drivers/media/usb/dvb-usb/pctv452e.c:20:0: drivers/media/usb/dvb-usb/pctv452e.c: In function 'pctv452e_frontend_attach': drivers/media/dvb-frontends/stb0899_drv.h:151:36: error: weak declaration of 'stb0899_attach' being applied to a already existing, static definition The problem is that the !IS_REACHABLE() declaration of stb0899_attach() is a 'static inline' definition that clashes with the weak definition. I further observed that the bugfix was only done for one of the five users of stb0899_attach(), the other four still have the problem. This reverts the bugfix and instead addresses the problem by not dropping the reference count when calling '->detach()', instead we call this function directly in dvb_frontend_put() before dropping the kref on the front-end. I first submitted this in early 2018, and after some discussion it was apparently discarded. While there is a long-term plan in place, that plan is obviously not nearing completion yet, and the current kernel is still broken unless this patch is applied.

[PATCH 4.14] perf machine: Guard against NULL in machine__exit()

by Rantala, Tommi T. (Nokia - FI/Espoo)

From: Arnaldo Carvalho de Melo <acme(a)redhat.com> commit 4a2233b194c77ae1ea8304cb7c00b551de4313f0 upstream. A recent fix for 'perf trace' introduced a bug where machine__exit(trace->host) could be called while trace->host was still NULL, so make this more robust by guarding against NULL, just like free() does. The problem happens, for instance, when !root users try to run 'perf trace': [acme@jouet linux]$ trace Error: No permissions to read /sys/kernel/debug/tracing/events/raw_syscalls/sys_(enter|exit) Hint: Try 'sudo mount -o remount,mode=755 /sys/kernel/debug/tracing' perf: Segmentation fault Obtained 7 stack frames.

[PATCH] usb: xhci: dbc: get rid of global pointer

by Felipe Balbi

If we happen to have two XHCI controllers with DbC capability, then there's no hope this will ever work as the global pointer will be overwritten by the controller that probes last. Avoid this problem by keeping the tty_driver struct pointer inside struct xhci_dbc.
