2013-11-05drivers/rtc/rtc-hid-sensor-time.c: enable HID input processing earlyAlexander Holler
Enable the processing of HID input records before the RTC will be registered, in order to allow the RTC register function to read clock. Without doing that the clock can only be read after the probe function has finished. Signed-off-by: Alexander Holler <holler@ahsoftware.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

2013-11-05kfifo API type safetyStefani Seibold
This patch enhances the type safety for the kfifo API. It is now safe to put const data into a non const FIFO and the API will now generate a compiler warning when reading from the fifo where the destination address is pointing to a const variable. As a side effect the kfifo_put() does now expect the value of an element instead a pointer to the element. This was suggested Russell King. It make the handling of the kfifo_put easier since there is no need to create a helper variable for getting the address of a pointer or to pass integers of different sizes. IMHO the API break is okay, since there are currently only six users of kfifo_put(). The code is also cleaner by kicking out the "if (0)" expressions.

2013-11-05drivers: w1: make w1_slave::flags long to avoid memory corruptionMichal Nazarewicz
On architectures where long is more then 32 bits, modifying a 32-bit field with set_bit (and other atomic bit operations) may cause bytes following the field to by modified. Because the endianness of the bits within a field is the native endianness of the CPU[1], on big-endian machines, bit number zero is in the last byte of the field. Therefore, `set_bit(0, ptr)' on a 64-bit big-endian machine is roughly equivalent to `((char *)ptr)[7] |= 1', and since w1 driver uses a 32-bit field for holding the flags, this causes bytes beyond the field to be modified. [1] From Documentation/atomic_ops.txt: Native atomic bit operations are defined to operate on objects aligned to the size of an "unsigned long" C data type, and are least of that size. The endianness of the bits within each "unsigned long" are the native endianness of the cpu.

2013-11-05drivers/memstick/core/mspro_block.c: fix attributes array allocationMichal Nazarewicz
attrs field of attribute_group structure is a pointer to a pointer (as in an array of pointers) rather than pointer to attribute struct (as in an array of structures), so when allocating size of the pointer sholud be used instead of the structure it is pointing to. While at it, also change the call to use kcalloc rather than kzalloc.
