SPI: SpiDevice `aquireMaster(ctx)` and `releaseMaster(ctx)` now require context.
releaseMaster() now returns if the master has been released in this context.
SPI: Fix aquire bug in all implementations.
CO: Fix coroutines macros for inheritance from template class.
Typo.
Driver: Add LIS302DL accelerometer driver.
This chip can be used with either an I2C or a SPI transport layer.
Examples: Add LIS302DL example application for STM32F4 Discovery.
This example simply shows the acceleration vector using the four on board LEDs.
