Subject[PATCH v3 0/1] can: ucan: add driver for Theobroma Systems UCAN devices
Date
This is v3 of the Theobroma Systems CAN/USB adapter driver
upstreaming effort.

Featured v2 -> v3 changes:
* count error frames as data packets
* use canid_t for all can ids
* use BIT(x) instead of (1 << x)
* use __le16 / __le32 for little-endian fields
* add spinlock around context allocation (fixes a possible race)
* fix comment style
* use WARN_ON return value
* fix state logic bug that did not allow return to ERROR_ACTIVE
* drop echo_index from context_array (not needed)
* rename "tx_contexts" -> "context_array" to prevent confusion
* add __func__ to all errors and warnings, and to info where it made sense
