Subject: [PATCH v2 00/12] Fix {rx,tx}_errors CAN statistics

This series extends the patch 4d6d26537940 ("can: c_can: fix {rx,tx}_errors statistics"),
already merged into the mainline, to other CAN devices that similarly do
not correctly increment the error counters for reception/transmission.

Changes in v2:
- Fix patches 7 through 12 to ensure that statistics are updated even
  if the allocation of skb fails.
- Add five new patches (i. e. 1-5), created during the further analysis
  of the code while correcting patches from the v1 series (i. e. 7-12).

Dario Binacchi (12):
  can: c_can: update statistics if skb allocation fails
  can: sun4i_can: call can_change_state() even if cf is NULL
  can: sun4i_can: continue to use likely() to check skb
  can: hi311x: fix txerr and rxerr reporting
  can: hi311x: update state error statistics if skb allocation fails
  can: m_can: fix {rx,tx}_errors statistics
  can: ifi_canfd: fix {rx,tx}_errors statistics
  can: hi311x: fix {rx,tx}_errors statistics
  can: sja1000: fix {rx,tx}_errors statistics
  can: sun4i_can: fix {rx,tx}_errors statistics
  can: ems_usb: fix {rx,tx}_errors statistics
  can: f81604: fix {rx,tx}_errors statistics
