2012-09-06usb: gadget: s3c-hsotg.c: fix error return codeJulia Lawall
Convert a 0 error return code to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier ret; expression e,e1,e2,e3,e4,x; @@ ( if (\(ret != 0\|ret < 0\) || ...) { ... return ...; } | ret = 0 ) ... when != ret = e1 *x = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\|ioremap\|ioremap_nocache\|devm_ioremap\|devm_ioremap_nocache\)(...); ... when != x = e2 when != ret = e3 *if (x == NULL || ...) { ... when != ret = e4 * return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Felipe Balbi <balbi@ti.com>
2012-09-06usb: dwc3: ep0: correct cache sync issue in case of ep0_bouncedPratyush Anand
In case of ep0 out, if length is not aligned to maxpacket size then we use dwc->ep_bounce_addr for dma transfer and not request->dma. Since, we have alreday done memcpy from dwc->ep0_bounce to request->buf, so we do not need to issue cache sync function. In fact, cache sync function will bring wrong data in request->buf from request->dma in this scenario. So, cache sync function must not be executed in case of ep0 bounced.

2012-09-06perf test: Add round trip test for sw and hw event namesArnaldo Carvalho de Melo
It basically traverses the hardware and software event name arrays creating an evlist with all events, then it uses perf_evsel__name to check that the name is the expected one. With it I noticed this problem: [root@sandy ~]# perf test 10 10: roundtrip evsel->name check:invalid or unsupported event: 'CPU-migrations' Run 'perf list' for a list of valid events FAILED! Changed it to "cpu-migrations" in the software event arrays and it worked.

2012-09-06NFSv4: Fix buffer overflow checking in __nfs4_get_acl_uncachedTrond Myklebust
Pass the checks made by decode_getacl back to __nfs4_get_acl_uncached so that it knows if the acl has been truncated. The current overflow checking is broken, resulting in Oopses on user-triggered nfs4_getfacl calls, and is opaque to the point where several attempts at fixing it have failed. This patch tries to clean up the code in addition to fixing the Oopses by ensuring that the overflow checks are performed in a single place (decode_getacl). If the overflow check failed, we will still be able to report the acl length, but at least we will no longer attempt to cache the acl or copy the truncated contents to user space.

2012-09-06ALSA: usb-audio: Fix bogus error messages for delay accountingTakashi Iwai
The recent fix for the missing fine delayed time adjustment gives strange error messages at each start of the playback stream, such as delay: estimated 0, actual 352 delay: estimated 353, actual 705 These come from the sanity check in retire_playback_urb(). Before the stream is activated via start_endpoints(), a few silent packets have been already sent. And at this point the delay account is still in the state as if the new packets are just queued, so the driver gets confused and spews the bogus error messages. For fixing the issue, we just need to check whether the received packet is valid, whether it's zero sized or not.

2012-09-06ASoC: samsung dma - Don't indicate support for pause/resume.Dylan Reid
The pause and resume operations indicate that the stream can be un-paused/resumed from the exact location they were paused/suspended. This is not true for this driver, the pause and suspend triggers share the same code path with stop, they flush all pending DMA transfers. This drops all pending samples. The pause_release/resume triggers are the same as start, except that prepare won't be called beforehand, nothing will be enqueued to the DMA engine and nothing will happen (no audio). Removing the pause flag will let apps know that it isn't supported. Removing the resume flag will cause user space to call prepare and start instead of resume, so audio will continue playing when the system wakes up. Before removing the pause and resume flags, I tested this on an exynos 5250, using 'aplay -i'. Pause/un-pause leads to silence followed by a write error. Suspend/resume testing led to the same result. Removing the two flags fixes suspend/resume (since snd_pcm_prepare is called again). And leads to a proper reporting of pause not supported.

If the subchannel event function is called from IRQ context and we observe that the subchannel in question is gone we flag the attached device as not operational and schedule the event function to be called again from process context where the subchannel gets deregistered. However if the subchannel reappeared at the time the event function gets called from process context we would do nothing and leave the device in not operational state.

Because of the user address range check, that in turn then causes an EFAULT due to the user pointer range checking failing for the kernel address. Incorrectly resuling in a failed system call for 32-bit processes with a 64-bit kernel.

If the number of ports present on the SoC/board is not the maximum and that the platform data is not filled with all data, there is an easy way to mess the PIO setup for this interface. This quick fix addresses mis-configuration in USB host platform data that is common in at91 boards since commit 0ee6d1e (USB: ohci-at91: change maximum number of ports) that did not modified the associatd board files.

2012-09-06regulator: lp872x: remove unnecessary functionKim, Milo
The lp872x_check_dvs_validity() is used for checking DVS platform data. If the DVS platform data is not defined, return as error code. Now, this is unnecessary because the default DVS mode is set in this case. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-09-06regulator: lp872x: fix NULL pointer access problemKim, Milo
The lp872x_set_dvs() is used for changing the DVS pin state. This function works only when the DVS platform data is defined. So don't assume that DVS data is always valid. In case the platform data is not defined, the DVS data is set to NULL for skipping the DVS pin control. DVS selection and GPIO pin number are used for the LP872x DVS pin control. For better readability, DVS selection argument is added in lp872x_set_dvs(). Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-09-06regulator: lp872x: initialize the DVS modeKim, Milo
The platform specific configuration(general_config) is optional. However, the DVS settings should be configured explicitly while loading the driver. This patch enables configuring the default DVS mode even though the platform data is not defined.

Commit b69cc672052540 added support for the E-861. After acquiring a C-867, I realised that every Physik Instrumente's device has a different PID. They are listed in the Windows device driver's .inf file. So here are all PIDs for the current (and probably future) USB devices from Physik Instrumente. Compiled, but only actually tested on the E-861 and C-867.

2012-09-05workqueue: fix possible deadlock in idle worker rebindingTejun Heo
Currently, rebind_workers() and idle_worker_rebind() are two-way interlocked. rebind_workers() waits for idle workers to finish rebinding and rebound idle workers wait for rebind_workers() to finish rebinding busy workers before proceeding. Unfortunately, this isn't enough. The second wait from idle workers is implemented as follows. wait_event(gcwq->rebind_hold, !(worker->flags & WORKER_REBIND)); rebind_workers() clears WORKER_REBIND, wakes up the idle workers and then returns. If CPU hotplug cycle happens again before one of the idle workers finishes the above wait_event(), rebind_workers() will repeat the first part of the handshake - set WORKER_REBIND again and wait for the idle worker to finish rebinding - and this leads to deadlock because the idle worker would be waiting for WORKER_REBIND to clear. This is fixed by adding another interlocking step at the end - rebind_workers() now waits for all the idle workers to finish the above WORKER_REBIND wait before returning. This ensures that all rebinding steps are complete on all idle workers before the next hotplug cycle can happen. This problem was diagnosed by Lai Jiangshan who also posted a patch to fix the issue, upon which this patch is based. This is the minimal fix and further patches are scheduled for the next merge window to simplify the CPU hotplug path.
