2016-03-11staging: lustre: obdclass: Use list_for_each_entry_safeBhaktipriya Shridhar1-3/+2
Doubly linked lists which are iterated using list_empty and list_entry macros have been replaced with list_for_each_entry_safe macro. This makes the iteration simpler and more readable. This patch replaces the while loop containing list_empty and list_entry with list_for_each_entry_safe. This was done with Coccinelle. @@ expression E1; identifier I1, I2; type T; iterator name list_for_each_entry_safe; @@ T *I1; + T *tmp; ... - while (list_empty(&E1) == 0) + list_for_each_entry_safe (I1, tmp, &E1, I2) { ...when != T *I1; - I1 = list_entry(E1.next, T, I2); ... } Signed-off-by: Bhaktipriya Shridhar <bhaktipriya96@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-03-11staging: iio: adc: Replace of_iomap() with devm_ioremap_resource()Amitoj Kaur Chawla1-10/+8
The adc driver uses of_iomap() which doesn't request the resource and isn't device managed so error handling is needed. of_iomap() is mainly used in cases where there is no driver or struct device so a switch to devm_ functions is required. This patch switches to use devm_ioremap_resource() instead which automatically requests the resource and is freed when the driver detaches. Removed the error handling to unmap I/O registers i.e. iounmap() in probe and remove functions of this driver and consequently removed an unnecessary label.

2016-03-11staging: fsl-mc: bus: Eliminate double function callBhaktipriya Shridhar1-2/+0
A call to irq_find_matching_host was already made and the result has been stored in mc_msi_domain. mc_msi_domain is again reassigned using the same function call which is redundant. irq_find_matching_host returns/locates a domain for a given fwnode. The domain is identified using device node and bus_token(if several domains have same device node but different purposes they can be distinguished using bus-specific token). http://www.bricktou.com/include/linux/irqdomain_irq_find_matching_host_en.html Also, of_property_read_bool finds and reads a boolean from a property device node from which the property value is to be read. It doesn't alter the device node. http://lists.infradead.org/pipermail/linux-arm-kernel/2012-February/083698.html Since, both the function calls have the same device node and bus_token, the return values shall be the same. Hence, the second call has been removed.

2016-03-11staging/android/ion : fix a race condition in the ion driverEunTaik Lee1-13/+42
There is a use-after-free problem in the ion driver. This is caused by a race condition in the ion_ioctl() function. A handle has ref count of 1 and two tasks on different cpus calls ION_IOC_FREE simultaneously. cpu 0 cpu 1 ------------------------------------------------------- ion_handle_get_by_id() (ref == 2) ion_handle_get_by_id() (ref == 3) ion_free() (ref == 2) ion_handle_put() (ref == 1) ion_free() (ref == 0 so ion_handle_destroy() is called and the handle is freed.) ion_handle_put() is called and it decreases the slub's next free pointer The problem is detected as an unaligned access in the spin lock functions since it uses load exclusive instruction. In some cases it corrupts the slub's free pointer which causes a mis-aligned access to the next free pointer.(kmalloc returns a pointer like ffffc0745b4580aa). And it causes lots of other hard-to-debug problems. This symptom is caused since the first member in the ion_handle structure is the reference count and the ion driver decrements the reference after it has been freed. To fix this problem client->lock mutex is extended to protect all the codes that uses the handle.
