Sometimes VIDIOC_S_CROP ioctl doesn't work, soc-camera driver reports: soc-camera-pdrv soc-camera-pdrv.0: S_CROP denied: getting current crop failed The VIDIOC_G_CROP documentation states that the type field needs to be set to the respective buffer type when querying, so the check in .g_crop() of the subdevices returns -EINVAL if the type is not set properly. Here the uninitialized local variable 'current_crop' is passed to the .g_crop() and this leads to the observed error. Initialize the type field of the local 'current_crop' before get_crop call.

On systems where it cannot be assured that enough continous memory is available all the time it can be very useful to only allocate the memory once when it is needed the first time. Afterwards the initially allocated memory will be reused, so it is ensured that the memory will stay available until the driver is unloaded.

The tps65910_rtc data is registered as the platform driver data in _probe(= ). Therefore the tps65910_rtc should be used on unregistering the rtc device.

First I would give three observations which will be used later. Observation 1: if (delayed_work_pending(wq)) cancel_delayed_work(wq) This usage is wrong because the pending bit is cleared just before the work's fn is executed and if the function re-arms itself we might end up with the work still running. It's safe to call cancel_delayed_work_sync() even if the work is not queued at all. Observation 2: Use of INIT_DELAYED_WORK() Work needs to be initialized only once prior to (de/en)queueing. Observation 3: IFF_UP is set only after ndo_open is called Related race conditions: 1. Race between bonding_store_miimon() and bonding_store_arp_interval() Because of Obs.1 we can end up having both works enqueued. 2. Multiple races with INIT_DELAYED_WORK() Since the works are not protected by anything between INIT_DELAYED_WORK() and calls to (en/de)queue it is possible for races between the following functions: (races are also possible between the calls to INIT_DELAYED_WORK() and workqueue code) bonding_store_miimon() - bonding_store_arp_interval(), bond_close(), bond_open(), enqueued functions bonding_store_arp_interval() - bonding_store_miimon(), bond_close(), bond_open(), enqueued functions 3. By Obs.1 we need to change bond_cancel_all() Bugs 1 and 2 are fixed by moving all work initializations in bond_open which by Obs. 2 and Obs. 3 and the fact that we make sure that all works are cancelled in bond_close(), is guaranteed not to have any work enqueued. Also RTNL lock is now acquired in bonding_store_miimon/arp_interval so they can't race with bond_close and bond_open. The opposing work is cancelled only if the IFF_UP flag is set and it is cancelled unconditionally. The opposing work is already cancelled if the interface is down so no need to cancel it again. This way we don't need new synchronizations for the bonding workqueue. These bugs (and fixes) are tied together and belong in the same patch. Note: I have left 1 line intentionally over 80 characters (84) because I didn't like how it looks broken down. If you'd prefer it otherwise, then simply break it. v2: Make description text < 75 columns Signed-off-by: NNikolay Aleksandrov <nikolay@redhat.com> Signed-off-by: NJay Vosburgh <fubar@us.ibm.com> Signed-off-by: NDavid S.
