The lightbar driver never assigned the drvdata in probe method, and thus there is nothing there. Need to get the ec_dev from the parent's drvdata. Signed-off-by:

The current implementation of the event queue both wastes space using a doubly linked list and isn't super obvious in how it behaves. This converts the queue to an actual circular buffer. The size of the queue is a tunable module parameter. This also fixes a few other things: - A memory leak that occurred when the ACPI device was removed, but the events were not freed from the queue. - Now kfree() the oldest event from outside all locks. - Add newline to logging messages. - Add helper macros to calculate size of events. - Remove unneeded lock around a check for dev_data->exist in hangup_device(). - Remove an unneeded null event pointer check in enqueue_events(). - Correct some comments.

On many boards, communication between the kernel and the Embedded Controller happens over an LPC bus. In these cases, the kernel config CONFIG_CROS_EC_LPC is enabled. Some of these LPC boards contain a Microchip Embedded Controller (MEC) that is different from the regular EC. On these devices, the same LPC bus is used, but the protocol is a little different. In these cases, the CONFIG_CROS_EC_LPC_MEC kernel config is enabled. Currently, the kernel decides at compile-time whether or not to use the MEC variant, and, when that kernel option is selected it breaks the other boards. We would like a kind of runtime detection to avoid this. This patch adds that detection mechanism by probing the protocol at runtime, first we assume that a MEC variant is connected, and if the protocol fails it fallbacks to the regular EC. This adds a bit of overload because we try to read twice on those LPC boards that doesn't contain a MEC variant, but is a better solution than having to select the EC variant at compile-time. While here also fix the alignment in Kconfig file for this config option replacing the spaces by tabs. Signed-off-by:

The cros_ec_lpc_reg files are only used by the cros_ec_lpc core and there isn't logical separation between them. So, merge those files into the cros_ec_lpc also allowing us to drop the header file used for the interface between the two. Signed-off-by:
