Biju Das <biju.das.jz@bp.renesas.com> says:

This patch series fixes the below issues in R-Car CAN-FD driver.

1) Race condition in CAN driver under heavy CAN load condition
   with both channels enabled results in IRQ storm on global FIFO
   receive IRQ line.
2) Add channel specific TX interrupts handling for RZ/G2L SoC as it has
   separate IRQ lines for each TX.

changes since v1: https://lore.kernel.org/all/20221022081503.1051257-1-biju.das.jz@bp.renesas.com
 * Added check for IRQ active and enabled before handling the IRQ on a
   particular channel.
