2013-09-18cpufreq: unlock correct rwsem while updating policy->cpuViresh Kumar
Current code looks like this: WARN_ON(lock_policy_rwsem_write(cpu)); update_policy_cpu(policy, new_cpu); unlock_policy_rwsem_write(cpu); {lock|unlock}_policy_rwsem_write(cpu) takes/releases policy->cpu's rwsem. Because cpu is changing with the call to update_policy_cpu(), the unlock_policy_rwsem_write() will release the incorrect lock. The right solution would be to release the same lock as was taken earlier. Also update_policy_cpu() was also called from cpufreq_add_dev() without any locks and so its better if we move this locking to inside update_policy_cpu(). This patch fixes a regression introduced in 3.12 by commit f9ba680d23 (cpufreq: Extract the handover of policy cpu to a helper function).

2013-09-18cpufreq: Clear policy->cpus bits in __cpufreq_remove_dev_finish()Viresh Kumar
This broke after a recent change "cedb70a cpufreq: Split __cpufreq_remove_dev() into two parts" from Srivatsa. Consider a scenario where we have two CPUs in a policy (0 & 1) and we are removing CPU 1. On the call to __cpufreq_remove_dev_prepare() we have cleared 1 from policy->cpus and now on a call to __cpufreq_remove_dev_finish() we read cpumask_weight of policy->cpus, which will come as 1 and this code will behave as if we are removing the last CPU from policy :) Fix it by clearing the CPU mask in __cpufreq_remove_dev_finish() instead of __cpufreq_remove_dev_prepare().

2013-09-17USB: pl2303: distinguish between original and cloned HX chipsFrank Schäfer
According to Prolific, several (unauthorized) cheap and less functional clones of the PL2303HX chip are in circulation. [1] I've had the chance to test such a cloned device and it turned out that it doesn't support any baud rates above 115200 baud (original: 6 Mbaud) It also doesn't support the divisior based baud rate encoding method, so no continuous baud rate adjustment is possible. Nevertheless, these devices have been working (unintentionally) with the driver up to commit 61fa8d694b ("pl2303: also use the divisor based baud rate encoding method for baud rates < 115200 with HX chips"), and this commit broke support for them. Fortunately, it is pretty simple to distinguish between the original and the cloned HX chips, so I've added a check and an extra chip type to keep the clones working. The same check is used by the latest Prolific Windows driver, so it should be solid.

2013-09-17usb: s3c-hsotg: fix unregistration functionMarek Szyprowski
After driver conversion to udc_start/udc_stop infrastructure (commit "usb:hsotg:samsung: Use new udc_start and udc_stop callbacks" f65f0f1098) the gadget unregistration function is almost always called with 'driver' parameter being NULL, what caused that the unregistration code has not been executed at all. This is a leftover from the earlier verison of this function (which used simple start/stop interface), where driver parameter was obligatory. This patch removes the NULL check for the 'driver' pointer and removes all dereferences of it. It also moves disabling voltage regulators out of the atomic context, because handling regulators (which are usually i2c devices) might require sleeping.

2013-09-17usb: gadget: f_mass_storage: reset endpoint driver data when disabledPeter Oh
Gadgets endpoint driver data is a criteria to judge that whether the endpoints are in use or not. When gadget gets assigned an endpoint from endpoint list, they check its driver data if the driver data is NULL. If the driver data is not NULL then they regard it as in use. Therefore all of gadgets should reset their endpoints driver data to NULL as they are disabled. Otherwise it causes a leak of endpoint resource.

2013-09-17usb: gadget: fix a bug and a WARN_ON in dummy-hcdAlan Stern
This patch fixes a NULL pointer dereference and a WARN_ON in dummy-hcd. These things were the result of moving to the UDC core framework, and possibly of changes to that framework. Now unloading a gadget driver causes the UDC to be stopped after the gadget driver is unbound, not before. Therefore the "driver" argument to dummy_udc_stop() can be NULL, so we must not try to print the driver's name without checking first. Also, the UDC framework automatically unregisters the gadget when the UDC is deleted. Therefore a sysfs attribute file attached to the gadget must be removed before the UDC is deleted, not after.
