This disadvantage of having it interruptible is that it would appear to work OK in most situations, but in the rare case that this call does fail, it can lead to misconfiguration of the AB, such as a regulator not being turned off and leading to a platform power consumption increase. There's no real benefit to having this interruptible. Make it a plain mutex_lock. The non-interruptability matches other low-level I/O functions such as SPI and I2C.
