3.16.50-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Mark Brown <broonie@xxxxxxxxxx> commit d555ea05f9d8ebf567eaa6b4e4cb5776aacf2940 upstream. When building on 64 bit architectures the use of bitwise negation generates constants larger than 32 bits which won't fit in u32s used to represent 32 bit register values on the device. Explicitly cast to let the compiler know that the higher bits are not significant and can be discarded.
