2014-07-09mfd: cros_ec: Use the proper size when looking at the cros_ec_i2c resultDoug Anderson
We know how many bytes the EC should be sending us (which is also the number of bytes transferred) and also how many bytes the EC actually wanted to send to us. When computing the checksum and copying back data let's make sure we take the lesser of the two of those. We'll also complain if the EC tried to send us too many bytes. The EC sending us too few bytes is legit for when we send the EC an invalid command. This is based on similar code in cros_ec_spi.

2014-07-09mfd: cros_ec: Move EC interrupt to cros_ec_keybAndrew Bresticker
If we receive EC interrupts after the cros_ec driver has probed, but before the cros_ec_keyb driver has probed, the cros_ec IRQ handler will not run the cros_ec_keyb notifier and the EC will leave the IRQ line asserted. The cros_ec IRQ handler then returns IRQ_HANDLED and the resulting flood of interrupts causes the machine to hang. Since the EC interrupt is currently only used for the keyboard, move the setup and handling of the EC interrupt to the cros_ec_keyb driver.
