Merge tag 'fixes-for-3.13a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes: First round of fixes for IIO in the 3.13 cycle. The usual mixed bag of fixes. * 3 cases where kconfig dependencies were missing. We need to keep a closer eye on this in new drivers. * hid_sensors was abusing the iio_dev->trigger pointer. We had a round of clearing this out some time ago but this driver clearly slipped through. * A misuse of the IIO_ST macro, in mcp3422, which we should really make a concertive effort to finish removing. * Avoid a double free introduced by recent buffer reference counting in the one driver that (quite reasonably!) does things differently (am335x) * A missing mutex_unlock in kxsd9 that means that driver has been non functional for some time and no one noticed (including me who for once actually has one of the supported devices). * An incorrect assumption about the parameters of sign_extend32 in mcp3422. So nothing controversial. The only substantial patch is the hid_sensors one and that is actually just adding a new pointer to the devices private state then moving the code over to it.
